VPN problems in a PC behind an ETEC PT-3818 router based on Conexant AMX-CA61E chipset

I'm trying to access my computer in Portugal using a VPN. Here in the UK I have a ETEC PT-3818 router with the DMZ option enabled for the IP address of my computer (, for instance this is enough to run eMule without port fowarding that I had to do in the past to get maximum speed downloading. No port is forwarded in the Virtual Server. I have all the VPN client and server well installed on both computers. I can ping my host computer in Portugal and receive the answer.

If I use this one in the UK as the Server and connect from Portugal using a client I can access my drives in this PC from Portugal, but the opposite doesn't happen. I always get Error 800 when I try to connect. I don't know what to do more and I really hope this is enough information to get some help. If not I'm here to answer all questions. Sorry if the English seems too confuse.

Thanks in advance

Make sure you have the builtin firewall on both computers disabled. Are you running any other firwall software i.e. zonealarm, norton personal firewall etc.?

2 things to check.
Make sure the firmware is up to date on the routers. Microsoft says that this is a router firmware issue.
Also if you are running NAT you might need to download this and try it.;en-us;818043
