Ok i don't understand. When i check my ports they are all closed, but 3389 RDC and no matter what i do i can't get port 21 to forward. To forward port 3389,which was blocked, all i did was add it to the router and i work first time. i have done the same with port 21 and this has not worked. Just to try to get to the root of the problem i have disabled the firewall in the router, disabled windows firewall, enabled DMZ to that computers ip and i checked that my isp was not blocking the port. What else could cause a Connection Refused error?
