I have a Cox cable modem and a Linksys router. If I connect directly with one computer to the modem, my Microsoft PPTP VPN client works fine. When I put the router in the middle, I can see the clinet hit my vpn router to try to open a tunnel but the connection attempt times out. Spent 2 hours with Linksys but no luck--they said the router was bad so got a replacement and, of course, it did the same thing. I have had success doing this with other Linksys routers even with multiple clients accessing my office vpn at the same time. Have tried all the normal stuff--checking the vpn passthru boxes, forwarding ports, putting in the dmz, etc. but nothing works. Have seen many, many issues with this. Should I just give up on Linksys and try a Netgear ?
