I am at a remote site - inwhich which all users connect to the main office via individual VPN clients (temp situation for next 2 months). After approx 20 minutes, no traffic seems to go through the PPTP tunnel. If I disconnect, then re-connect all works well. I don't know if one of the ISA boxes are to blame. My laptop is also connected to the main office, with the same applications opened and I have no problems. Main Office Firewall: Windows 2003, ISA 2004. Remote Office Firewall: Windows 2003, ISA 2000. Help! Please Help!
