Like I said, it can take up to 6 retries to successfully connect to our RAS servers (up to 30 retries if the remote user is behind a Linksys router). Port 47 (tcp or udp) has nothing to do with VPN. check over here

We appreciate your feedback. The other network interfaces are those that have been on the machine since it was new, and never caused a problem ad Mariodlg suggested might be a cause.

Routes for the subnets are implemented either through static routing entries or through a routing protocol, such as Routing Information Protocol (RIP). check my blog Why was Vader surprised that Obi-Wan's body disappeared?

Ip-address is the externally known IP-address of ISA. The VPN client must have a valid computer certificate installed that was issued by a CA that follows a valid certificate chain from the issuing CA up to a root CA rejohn Long Path Tool help me a lot when i have an issue like file deleting or renaming the file. The certificate revocation validation only works as well as the CRL publishing and distribution system.

Any insight into the VPN process would be helpful. Your name or email address: Do you already have an account? There's nothing in either router's firewall which would prevent one the remote IP but not my work IP. have a peek at these guys Please try again later.

At some point in the past, the remote PCs were successfully logged onto the domain, so now log into that (but obviously can't connect). To allow PPTP traffic, configure the network firewall to open TCP port 1723 and to forward IP protocol 47 for Generic Routing Encapsulation (GRE) traffic to the VPN server.
