Okay, I have Comcast, connected to the WAN port of a Linksys WRT300N Router. I set up a Windows Server 2003 box to accept incoming VPN connections via Routing and Remote Access. Now, every time I establish a VPN connection, in some networks, I get error 619, but on this particular network, it works perfectly for until about 5 minuites later of use, the VPN keeps Dropping. Why Does It Do That!!!!
Okay, I triggered port 1723, 500, 4500 and 10000. Everything in the firewall security tab is unchecked. SPI Firewall is disabled. VPN Passthrough is all set to 'Enabled'.
I think its the router issue. How do I fix this problem?
I don't have much experience with VPNs but I would start with the event viewer. start, run, eventvwr.msc
