Question : ISA 2000 VPN Gateways - Unable to ping hosts on the remote site

I have a Windows 2003 domain.  There are two geographical sites.  At the main site I have a ISA 2000 server. At the other site I have an ISA 2000 Server.

I have set them up a VPN Gateways.  I can successfully create the connection, but am unable to ping in either direction to any IP address.

ISA Server at main office have an internal and external network card.  The external network card is attached to an ADSL router that is configure to forward everything to the external NIC on the ISA Server

ISA Server at the remote site has one NIC and is connected to an ADSL router which is configured to forward all traffic to the NIC on the ISA server.

I suspect the issue is a routing one.  Any help appreciated.

Are you blocking icmp traffic anywhere in the firewall rules/system policy?
