Hi,
I have been working on a config for a 4G service on a SRX320 for a few days now, but I have come across one main things that has me stumped and a few other things that I am scratching my head over.
The first is the the IP address assigned to the 4G service (xxx.xxx.29.191/32) is allocated by the SP (which is me) and is a normal everyday /32 public IP address. The IP address gets assigned, and the service works, but when I look in the SRX's routing table, it sees the netmask as a /25 not a /32 as assigned. So I'm not sure what's going on here...
The default route is also interesting, I configured it as 0.0.0.0/0 nexthop dl0.0 - and the routing table it's nexthop IP address for the default route is xxx.xxx.29.192 - which isn't right to me, but, the funny thing is the service works fine - traffic comes in and traffic goes out normally.
The main problem I have is that I need to run BGP across the 4G service to the SP, but I can not get a session established, but, more worryingly, I can not telnet on port 179 to the SP equipment from th SRX - it just times out. I'm reasonably sure that the filters are setup correctly to allow BGP to establish. From my debug, it states that a socket to the host couldn't be opened - which I'll admit sounds just like a filtering issue, but I've been over and over it, allowing BGP and even all traffic types, but the issue remains. A telnet in the reverse direction (from the SP back into the SRX) connects fine.
I know the SP side of things is fine as I configured and used a Cisco to achieve the desired result with out an issue.
This feels like a bug, but...
Any help would be greatly appreciated.
