We have a Checkpoint NG FP2 firewall with several VPN tunnels coming into it, all work fine except for two, which connect to PIX 501s.
All seems to work OK, however after a period of inactivity (normally overnight) they are unable to access HTTP through the tunnel. Other applications (Lotus, remote control etc) appear to be OK, only web traffic seems to be affected.
I'm finding very little information to help me troubleshoot the problem.
If anyone could suggest some good sources of information (yes, I’ve checked Cisco’s online documentation and searched TAC! :) I would be grateful. Any handy commands to help me see what’s going on would also be appreciated.
A few more details:
Running PIX IOS 6.3(1)
All traffic is routed through the tunnel, no other routing or tunnels are defined.
We’re using 3DES, SHA1, DH 2.
