1st I'm trying to set up the router for use with a VPN solution. I need UDP service for port 500 and 4500 and L2TP VPN pass through. I've set up port range forward for the ports in question and have enabled L2TP VPN pass through. - Doesn't work. 2nd I can't close the firewall for incoming HTTPS. Using ShieldsUp on the internet I can see port 443 is open and I can't find out how to close it. In trying to find a solution to my first problem, I shut down the firewall - strangely it seems that it didn't have any effect. Using ShieldsUp I still got the results that all ports are either closed or stealth, except port 443 (HTTPS) that is open. My conclusion is that it seems I can't control the firewall from the GUI. I'm running on firmware 2.00.05 (that's not available online anywhere - not even at LinkSys?!) VPN was working when I used my SUSE Linux box as router/firewall. Any ideas?
