That looks to be about right, assuming that the UDP connections always
follow a TCP connection. If the UDP connection doesn't necessarily follow
a TCP connection, then you'd need another Protocol Definition for just
UDP, and a matching Server Publishing Rule.

The internal server *must* have the SBS/ISA machine set as default gateway
(if it's not already) too.
