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 (10.0.0.3), 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
