Hi,
How can we be sure GRE is working?
We have an ISA2004 server that we want to use as a VPN server and
can not seem to connect.  Everything we read pretty much is saying to make
sure we have GRE enabled. 

What happens is when we try to connect from an external location via dialup
or a cable connection we get timed out with the 721.

Thanks
Steve
