[clug] VNC Connection

[Pilcher, Fred]

This isn't a strictly a Linux-related question, but I hope someone has
some ideas.

I've recently converted a friend from Windows to Kubuntu. To help with a
few configuration issues (the blind leading the even more blind) I
connected to her PC via VNC using krdc/krfb and all went well. A couple
of nights ago we needed to do it again to work through some stuff, but
couldn't.   

When we'd successfully connected earlier she had to put her PC into her
DMZ but last night, as soon as she did that her modem stopped responding
to pings, though she could ping me. When she moved out of the DMZ, her
modem responded to pings again. We tried it several times and the result
was consistent every time. Regardless of whether she was in the DMZ or
not, krfb on her end didn't indicate that I was trying to connect, and
krdc on my end just sat there waiting for a response from her PC.

If it hadn't worked previously I'd simply assume that I was just too
ignorant to do it. And the behaviour of her modem when she moved the PC
in and out of the DMZ just sounds weird.

She hadn't changed any settings since we'd connected successfully. I
could connect to other PCs on my home network using krdc/krfb. She's on
an ADSL connection via Netspeed and I'm on a cable connection via
Transact/Netspeed if that has any relevance.

Does anyone have any ideas?

Thanks,

Fred
