I'm trying to connect to a server via ftp with no luck. The server is running xp-pro sp2 with iis installed. I have enabled the firewall with exceptions for ports 20 and 21. I have also disable the Mcafee Personal firewall. The router is a linksys WRV54G and I have disabled its firewall and am forwarding both ports to the server's ip. The client is running xp-pro and using either cuteftp or ws_ftple. Both are recieving a error "rl-recv: Blocking call cancelled". I can disable and re-enable the firewalls and i get the same error. I've done some checking and it looks like my isp (Comcast) may be blocking port 20. I checked the ports using "Sheilds Up" website. It appears to change, meaning sometimes it looks blocked and other times it appears to be open. Is there a way to get around those 2 ports and use other ones. Any suggestions or ideas Thanks.
