Cisco 877 VPN site to site traffic problem

[StanUk]

Hey all,

I have 2 Cisco 877 Routers connected via a site to site VPN. The tunnel is up and i can ping across the network in both directions. However, i cannot remote desktop or connect to a domain on the other side. I have enabled the basic firewall on both sides, and created a rule to allow all traffic through the tunnel.

Any help is much appreciated.

Try changing the mtu speeds to 1492 on both routers. remember packets get fragmented thought a tunnel .I had this same problem on my 1800
