I'm trying to connect to my clients VPN Server from my laptop at the office. I can connect to my client's VPN server everywhere else but my office. We are using a ISA Firewall and it seems that it is blocking my connection out to my client. I real don't have any experience with ISA firewalls. But think I could figure out and suggestions to help me. Client is Win XP Pro. I'm using the IP address to connect to the VPN server not a host name.
