Hi
I have a Asus WL-520g wireless router connected to my NTL cable modem.
The cable moden is a NTL-Home 100,
I tried a VPN connection last week in the USA and everything worked fine.
When I try to connect to the VPN from my home I get a connection error

A connection between the VPN server and the VPN client has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets.

My question is does my router and/or NTL allow GRE

Thanks
