VPN site to site only working in 1 direction - 11.Mar.2008 3:49:54 PM

protocol: PPTP
network relation: tried both route and NAT
remote site: can connect to local site, ping and route successfully
Local Site: cannot connect to Remote

Things that I've tested:
On a laptop at the local site, I can connect to the remote site using site-to-site credentials and route,ping etc; so it cannot be incorrect username/password

On the local ISA 2006 server, I can telnet to the remote site and it connects?!? So I don't think it is the PIX 515 in front of the local ISA.

However, when i try to ping a remote machine ip from the local isa server, I get 1 timeout, then destination unreachable.

I have an access rule allowing all protocols from internal/lcoalhost to remote office network as well as back again.

On the remote ISA, i have a rule allowing all protocols to and from localhost/internal to local office.

I'm not sure what else to check, since I cannot find anything in the event viewer that gives me a clue as to where this is failing. Does anyone have any suggestions?

Thanks.
