I have had trouble getting the Linux Firefox GWT Developer Plugin working, so I figured I would just run Chrome in WinXP under VirtualBox and install the plugin there. However, I am having trouble with the connection.

Host: Mandriva Spring 2010.1 Guest: WinXP

Whether I have the guest configured with NAT or Bridged networking, I can ping my host from the guest using it's router-assigned IP number, which happens to be 192.168.0.105. However, when I run the GWT application in Linux, it sets up a service on port 8888 that I can see from Linux as either 127.0.0.1:8888 or 192.168.0.105:8888, but from the WinXP guest, it never loads any content from 192.168.0.5:8888.

Any idea why I can ping the host but not hit its Web service on port 8888?

My first guess would be the WinXP firewall. If I remember correctly, non-standard ports are not open by default. You would have to either completely drop the firewall or specifically open port 8888.

Turning off Windows Firewall did allow me to connect to the service at 192.168.0.5:8888. Oddly, however, the GWT Developer Plugin is failing to connect to the GWT server at 192.168.0.5:9997. –  Paul Aug 7 '10 at 19:07
