ISA & ultraVNC

Can someone assist? With the help of the SBS NG I have got part way with
this issue. Using ISA 2004 (fully SP/patched), as part of SBS2003R2 on a
dual NIC set up with an ADSL router to connect to internet and an
application we use gets support from its programmers via ultra VNC. This is
not working & I am fairly sure that it is an ISA issue. Apparently the vnc
acts as a server over possibly ports TCP 5500, 5800/5801 & 5900/5901,
therefore I set up a new ISA Rule, having configured a user defined protocol
set for vnc covering the above ports, by setting "allow", protocols being
"vnc" (my protocol set), set the Source as "Internal" and the Destination as
"Internet" & all users. Rule then created & appeared at the top of list(?)
However, it worked once & has not since! - I have recreated it - moved it
down the list (after a proibited sites rule) & various other things all to
no avail! Have also set redirections etc in the router in case it was
firewalling it + have tried setting the Windows Firewall on the client PC to
allow vnc ports but nothing helps!
Can anyone with experience of running VNC (in any of its flavours) behind
ISA talk me through this please!?
