I have a very strange situation. I have configured a VPN between two networks but a TCP application that should run through the tunnel is failing. The remote end is sending RST to the SYN. Below is the output of the network dump. I tried to reduce the MTU but with no success (the application runs through Cisco VPN client using dialup).
any clues what might be wrong? Thanx in advance.
Internet Protocol, Src Addr: 10.160.196.130 (10.160.196.130), Dst Addr: 126.96.36.199 (188.8.131.52)
I remember having come across a similar problem some time ago. Just as is the case here, the remote end was sending a RST to a SYN. The root in that case turned out to be the presence of CBAC. It seems that CBAC and a client initiated HTTP session don't go together. If you have CBAC configured, try removing the same and see if the setup works normally.
