Accessing Internal Server

Hi guys,
I have a SBS2003 box with ISA (mail.domain.com.au) and a published 2003
TS Box (support.domain.com.au - which also has some IIS6 sites published).

They have unique external IP's.

From the outside world everything works fine with SBS box...
Here is the strange part....from outside the only way I can start a
connection to the TS box(RDP/HTTP etc.) is IF i first make a connection of
some sort to the SBS box (then everything works for 10~15mins, then back to
square 1....

Any ideas??

Cheers

Kristian Yench

How are these boxes connected to the net?
