VPN tunnel does not allow all traffic to pass through
I have setup a VPN tunnel between a 515E & an 857 router. The tunnel is established via the internet and hosts on both ends can ping each other. The 515E is the hub device. All sites connect to this firewall. The 857 router is placed at a remote site.
The problem i have is that although the tunnel is established, it seems that the connectivity is not as it should be. When I run a port scan from one of the servers at the central site to a device on the remote site, the scan results tell me that none of the ports are open. For example I scanned the 857 router. Although it has telnet and http enabled, The scan result was that the host was alive but no ports are open. Because of this, I am unable to remotely administer WinXP desktops and network printers at the remote site. The pix firewall has sysopt enabled. I have not enabled the firewall feature on the router neither have i added any access lists which would cause any traffic restrictions. Can you think of any reason why this behaviour would occur?
