XP Remote Desktop - works on LAN but not WAN I have been struggling to get Remote Desktop to work properly for me & would really appreciate some help. I am trying to be able to connect from my work laptop to my home machine when on the road. I set up router to forward port 3389 (TCP) to the XP machine's IP address. If I hook up laptop to the HOME LAN and try to access another desktop by typing IP address (ie. 192.168.1.xxx), no problems. But, if I try to connect using the router's WAN IP (ie. 65.61.xxx.yyy), or my DynDns name (ie. Joe.homeip.net), I cannot connect. Funny thing is, If I use a dialup modem connection instead, Joe.homeip.net works no problem! I am confused... Things I tried: 1. Checked port forwarding in router, seems ok 2. Checked DynDns setup, not problem. 3. Can ping and get reply from 65.61.xxx.yyy), or my DynDns name (ie. Joe.homeip.net) 4. Remove ZoneAlarm &/or reset port forwarding. Doesnt not work w/ or w/o ZA. 5. Tried to dial in using modem connection to ISP & connect using Joe.homeip.net -- it works! NETWORK SETUP is: Cable Modem: RCA Protocols: TCPIP, and NETBUI for file/printer sharing Router: RCA, 192.168.1.1, DHCP enabled, TCP port 3389 forwarded to 192.168.1.xxx Wireless Router: DLink DI623, DHCP dissabled (using as switch only). Hardwire connected DynDns to handle DNS translation to local IP. RoadRunner ISP \\ RCA CABLE MODEM \\ RCA ROUTER \\ DLINK DI624 == [ W2K Laptop client ] -- telephone modem --> (DHCP off) \\ (zone alarm) [ XP Machine1 host ] I am really confused about the why external WAN is not working, but the phone modem is working. Tips on how to troubleshoot (and trace port traffic would be a big help). Mike (a newbie in trouble...)
