IDEA 4.5.4 and debugging using socket transport through VPN issues

platform: Linux. JDK 1.4.2

I have a strange problem where while working at home through our VPN, and trying to launch debugger, I get the error:

"Check your run/debug configuraiton. Failed to establish connection to the target VM at '127.0.0.1:36158' using socket transport"

I don't think my VPN client blocks local access. I can't use shared memory debuggign neither as it isn't supported on Linux for IDEA.

I didn't see any where that I can twick the debugger parameters and try things like change "127.0.0.1" to my host IP, or etc. to try and find a work around.

Any ideas ?
