SRX 1400 "max initiated negotiations in progress"

$
0
0

Short question: Does anyone have any idea what causes SRX 1400 to only log this with ike debug enabled, not bringing up a VPN tunnel?

 

[Oct 6 13:22:29 PIC 1/1/0 KMD2][234.234.234.234 <-> 123.123.123.123] Reached max initiated negotiations in progress. Ignoring the request to trigger new negotiation
[Oct 6 13:22:33 PIC 1/1/0 KMD2][234.234.234.234 <-> 123.123.123.123] Received IKE Trigger message with local_gw_addr = 234.234.234.234 remote_gw_addr = 123.123.123.123

 

Looks like I have this problem with one particular routed VPN tunnel with three network pairs, doesn't matter if the tunnel is configured with traffic-selectors or as three different tunnels. Other tunnels on the same device seem to work just fine, even newer ones than this problematic one.

 

The devices are an SRX 1400 cluster, with some 50-100 active routed tunnels. The configuration maximums shouldn't be even close, as far as I know the limit should be like 5000 tunnels for SRX 1400?


LDAP Amplification

$
0
0

Hello ,

 

 

We are facing with 20Gbps + ldap amplification attacks , the images given below to show how it is an emergency issue. IP addresses are directly sending to the blackhole community so we are closing ip address directly , this is why it seems nearly 10g . But when they hit to one of whitelisted ip address we see that the attack is nearly 24 Gbps. 

 

We have avalibla link aggregation ports and connectivity to handle this traffic but the biggest problem is ldap is coming with fragmanted packets , there is no udp header in LDAP amp packets so it seems like that

 

traffic seems like :

xxxx.ZZZZ . -> . ourip:389

xxxx.0 . -> . ourip.0

 

first packet hits to 389 port and next packets are coming fragmanted , without the udp headers. So there seems no source and destination port information in packet. 

 

we can not block the fragmantation because we have stream customers. 

 

Any body knows a solution for this ?

Single source flood

$

0

Hello ,

 

We are facing with an issue on SRX 3600 , if some single source ip address starts a flood SRX creates a session for this connection on single core of SPU and what if the selected core is on the first SPU , it causing to 100% usage of this core and locking all the device easily . This is a known issue on any kernel based device. We have tested on 

Freebsd / Centos /debian ...etc. they all give the same result 

 

depending on the instructions on 

https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/general/npc-srx3k-npc.html

 

SRX NPC :

 it can drop traffic to or from a particular IP address 

 

I think it is sth. similar to ntuple filters on intel 82599 chips , but we can easily write a script on c / perl / python to detect flooder and block on other operating systems and block this kind of flooder before the packets arrive net_recv filter on kernel. 

 

Is there any possible way to do the same thing on srx , is there any possibility to block depending on PPS for /32 source  on NPC ?

 

 

Thank you

 

SRX 3600 Topology Question

Hello ,

 

Depending on the instructions below , we want to connect 2x10G link aggregation to the box. But each ioc has 10Gbps connectivity.

 

So what if i need 10+Gbps connection with upstream do i need to get each 10G links from different iocs ?

 

This are the bandwith limitation any body knows pps limitations ?

 

Each NPC can not bind to multiple iocs but on documetations it says 55gbps connectivity , what if we need 30Gbps connectivity , an npc limit is 20Gbps how you should connect 3 or more 10G link and let them bind in one aggregation port whil it does not supporting to go through an NPC ?

https://www.juniper.net/assets/cn/zh/local/pdf/datasheets/1000267-en.pdf

 

 

 

 

 

Each IOC binds to exactly one NPC
Multiple IOCs can be bound to one NPC
Multiple NPCs cannot bind to one IOC, each NPC will bind to a separate IOC

Each IOC has a 10 Gb full duplex connection to the fabric
Each SPC has a 10Gb full duplex connection to the fabric
Each NPC has two 10 Gb full duplex connections to the fabric: one towards the IOCs, and one towards the SPCs

eBGP Multihop - IPv4 and IPv6 Group

$
0
0

Hopefully a quick question for the guru's. 

 

I have a test network where I have dual-stack IPv4 and IPv6 with a neighbor that was directly connected. 

 

This was accomplished through the use of two neighbor statements, one with v4 and one with v6 address. 

 

To experiement with multi-hop, I put a "dumb" router in between the two (the other BGP end is a cisco 1941) and configured the loopback address and got multi-hop up and running, however I got a conflict when I tried to commit and had to remove the neighbor v6 address. 

 

'bgp'
Error in neighbor <IPv6 address here> of group external:
local and peer addresses must be from the same family
error: configuration check-out failed

When I tried to add a "local address" with a v6 address, it overwrote the v4 address? 

 

I am not sure if I am doing it incorrectly, or if I have to create a separate "group" to multihop over v6 from the v4 group, which is strange because when they are directly connected I can dual-stack the same group. 

 

Any thoughts? 

Pim dense mode on SRX and (*,G) State creation

$
0

Hi everyone,

 

Source 199.199.199.1-----  tun10 -Cisco-fe0/0/4---- Receiver ( 239.1.1.1)

 

On Cisco :

 

Source is not sending any multicast stream yet

As soon as LHR  receives IGMP report about 239..1.1.1, (*,239.1.1.1) is created that can be seen with show ip multicast route i.e we do not need to receive multicast stream from source to create (*,239.1.1.1) state. It is created as result of IGMP.

 

Now if we use the same setup on SRX:

Again source is not sending any multicast stream yet

Source 199.199.199.1-----  tun10 -SRX-fe0/0/4---- Receiver ( 239.1.1.1)

 

I noticed following:

 

1) ( *,239.1.1.1.)  state is not created in multicast table eventhough SRX is able to discover using IGMP , receiver is interested in 239.1.1.1, that can be seen using show igmp but multicast table does not show entry.

 

Now if contrast this with Cisco, Cisco creates ( *,239.1.1..1) state in multicast routing table once it receives IGMP report for 239.1.1.1 from Receiver.

 

Is that normal behavior on SRX?

 

 

2) Source  199.199.199.10 is sending stream at 239.1.1.1

 

SRX creates a ( S,G) state i.e ( 199.199.199.10, 239.1.1.1) which can be seen by using  show multicast route.

 

This behavior is common between Cisco and SRX.

 

 

3)  Do we have any command on SRX that can show me the number pf packet dropped because of RPF failure?

 

 

Thanks and have a nice weekend!!

Hi

 

I want to establish VPN with Cisco firewalls and other 3rd party vendors, the VPN ACL conatins a lot of hosts addresses which will require huge policies if I will configure policy-based VPN.

So can I use route-based VPN using traffic selectors?

Is this tested before?

 

Thanks

SRX question, bridge to switching environment

Do we still need to put secondary ip on srx same as netscreen?

$

Hi All,

 

Lets say the current screenos config have secondary ip on interface. The purpose of this secondary ip is because the ccurrent public ip address on the interface already full. In other word purposed for MIP. Example like below:

 

set interface ethernet2/1.420:1 ip 40.30.20.1 255.255.255.240

set interface ethernet2/1.420:1 ip 40.30.31.70 255.255.255.240 secondary

set interface ethernet2/1.420:1 ip 50.70.31.70 255.255.255.240 secondary

 

 

So in SRX do we need also put secondary ip on that interface? Or we just create the pool under source-nat / destination-nat?

 

Thanks and appreciate any feedback

SRX-550 upgrade fails, at compatibility check ! Read-only file system

Hello,
I have a issue at SRX-550 software upgrade, at compatibility check , does anybody has has the same issue ?

I need to upgrade a couple of SRX550M clusters from 15.1X49-D30.3 to 17.3.
At upgrade, compatibility check fails because the system tries to write on a 'read-only' directory.
The behavior is the same with 15.1X49-D110.

Dynamic VPN client having wrong netmask and blank default gateway

$
0
0

Hello,

 

I'm trying to set up VPN for a SRX550m unit.  I was able to establish connection (via Pulse Secure v5.1.5).  However, once connected, although the client's got the correct IP address assignment, its netmask is somehow set to 255.255.255.255 (it should be 255.255.255.0, aka /24), and on top of that, the default gateway is set to... blank!

 

I've stumbled upon a post (see link below) where the exact same issue was presented, but the solution (?) seemed to be downgrade to 11.1 R.4 -- but that was back in 2012.

 

http://forums.juniper.net/t5/SRX-Services-Gateway/Pulse-Clients-Getting-Wrong-Subnet-Mask/m-p/140005

 

I've inherited this SRX550m unit and it's currently in production mode so downgrading JunOS is definitely not a viable option.

 

I was hoping that Juniper would've fixed it by now, but it doesn't seem to be the case.  I hope that I'm wrong and that I've either missed an important step or fat-fingered something, and if so, please feel free to point out my mistakes.

 

Please find attached the configuration of the unit for your perusal.  Any advises/pointers would be very, very much appreciated.

 

PS: I am aware of Juniper have switched over to NCP client but that would require us to procure license and what-nots so I have to make this work with Pulse Secure.  (I hope that all of this is not a Pulse Secure bug of some sort...)

 

PPS: Also, unfortunately, along with the inheritance of this unit, I've also inherited not having a support contract with Juniper Support team so I couldn't ping them for assistance.  :-(

 

 Regards,

 

Changing Scheduling order of Queues on SRX 650

$
0

Hi everyone,

Please consider the following set up:

 

Let say we have mapped 8 traffic class to queues on our SRX 650

Traffic 0—Q0

Traffic 1-q1

Traffic2-q2

Traffic3 q3

Traffic4-q4

Traffic5-q5

Traffic-q6

Network Control-q7

 

If we do not define any scheduler,  will SRX  service queues from high to low queue using default scheduler?

How about if we want to modify this order for example:

 

Traffic 0—Q0

Traffic 1-q1 Scheduler 1, priority high

Traffic2-q2 Scheduler 2 priority low

Traffic3 q3 Scheduler 3 priority low

Traffic4-q4 Scheduler 4 priority low

Traffic5-q5 Scheduler 5 priority medium

Traffic-q6 scheduler 6 priority low

Network Control-q7 scheduler 7 priority low

 

Will the above config cause queues be serviced in following order?

Q1 first ( because Scheduler priority is high)

Q5 second ( because Scheduler priority is medium)

 

Then rest of them in these order

Q7

Q6

Q4

Q3

Q2

Q0

 

 

 

Thanks and have a nice day!!

Multifield filter and BA Classifier on SRX 650

$

0

 

Let say we have following scenario:

 

Traffic>----f1/0-SRX

 

We applied multified classiifer  ingress f1/0, which classifies traffic based on some criteria, what happens to traffic that is permitted  by Multified filter but not assigned to any forwarding class? is such traffic placed in best effort queue?

Example:

We have multifiled classfier:

 

 TERM 1 from TCP 80-- then  Forwading class Critica, then accept

TERM 2 from TCP 70-  then Forwarding class Bulk, then accept

TERM 3 from TCP 60 -> then accept ( i.e we did not assign any forwarding class)

 

Will traffic TCP 60 be placed in default queue as no forwarding class is specified  or is it subject to default Classifer applied on the Interface?

 

Thanks and have a nice day!!
