I have been trying different options to resolve an issue with a remote site VPN tunnel. I have the tunnel up and working. I have tried using IPSEC with low,medium and strict security profile. Since I am using Shiva VPN devices, I have tried using their Shiva Smart Tunnels too. They all work fine. I can perform all the normal operations like file copy, establish VNC sessions and browse interent too. The only problem is with the telnet session from that remote site to another site which goes through my comapny LAN. The telnet session works fine from the internal company LAN, but it doesnt work from that remote site. It starts of well allowing the users to log in, but once they log in, it freezes up. Initially I assumed this was caused by the encryption, but later on found out that its the checkpoint firewall on the company side that casues this problem. I am sure about this because I tried a different VPN connection via an ADSL connection that connected to the company LAN without going throught firewall. It worked perfectly fine allowing the telenet session.
Could anybody tell me what settings on checkpoint would resolve this issue.
