Hi guys,
we have this irritating issue that I have been strugling with before, going back to Sonicwall helped last time. sonicwall is at its last breath so now we need to implement SRX solution.
this is simple firewall with internett access and leased IPVPN from 3rd party company.
srx is at "location 1" same as the IPVPN router and are in same LAN(trust-zone). IPVPN is routing to 4-5 another VPN locations.
the resource-servers(windows terminal-server,file,print and so on) are located at "location 2" which is on one of the IPVPN-sites
we have:
added static routes to the IPVPN-sites on the srx
after testing we wasnt getting connection to the sites so we added trust-trust allow policy.
everything seemed fine, but people are getting these strange disconnections from terminal-server, as if you had problems with the wireless network and got disconnected for 5-20 of seconds then the connection recreate itself.
the connection status show low-strengh though its 1Gbps VPN
the ping is constantly replying with stable speed even when the rdp is in reconnecting state.
I also heard problems with printing and other 3rd party services.
the strange case is that when RDP-ing to a server on the internett there are no disconnects. the internet speed is as adviertised by ISP and internet-services(email, http) work as they should.
swtching back to old sonicwall fixes the issue and everything works as it should, go figure..
one thing I can mention is that "location 2" lan has portbased vlan, I changed the vlan-interface on the SRX to match the same vlan-id, I thought it could be easier to understand the topology, I really hope that this is not the evil root of it
------------
I've tried googling but is seems this isn't an issue out there, and I only find my own post from couple of years ago.
any help would be really appreciated!
