File transfer through second SSH?

[gumbald]

Not sure where the best place to put this was, but here goes...

I can SSH to the main server but not the ISO server externally. However, once logged into main server, I can then SSH to ISO server.

So, how can I transfer I file back to my computer, from the ISO server?

Didn't think it would be simple, I'll just have to wait until tomorrow for my Vista ISO then They haven't sent me my key yet, so can't install it anyway
