Thanks, it's pretty close to the same setup I had for the Cisco VPN
clients, I had defined as:

3389 TCP Outbound
4500 UDP Send Receive
500  UDP Send Receive

I can add 4500 UDP Receive Send in there to test it when she stops by
this afternoon, otherwise it looks like most of it is already in there.

The more I think about it though, it appears that it is going to be more
hassle than it is worth.  I think I'm going to set up a separate network
for her temporarily instead.  I have some dark fiber running down near
that area, I'll just throw some transceivers on there and give her an IP
on a range outside of our network.

Dan,

We had this issue quite some time ago and one of our guys found a setup
that
worked.  I don't know if it still holds water but it was so difficult to
track
down we ended up keeping it for future reference.  Below is a nutshell
of what
we've got to work without the FWC installed on our "visitors" computers.

The setup below applies to our ISA2000SE so I apologize if it doesn't
fit into
your 2004 configuration.  We have to wait until after April 15 to jerk
around
with our network (unless something breaks - crossing fingers).  If
you've got
other questions about my settings then just ask and I'll do my best to
pass it
along. [nd]

Protocol Definitions ->
Def. Name: IPSec NAT-T
Port Number: 4500
Port Type: UDP
Direction: Receive Send

Def. Name: IPSec IKE
Port Number: 500
Port Type: UDP
Direction: Send Receive

Protocol Rule ->
Allowed for the two definitions listed above

IP Packet Filters ->
Filter Name: ICMP Type 3, Code 4
Filter Type: Custom Filter
IP Protocol: ICMP
Direction: Both
Type: Fixed Type
Number: 3
Code: Fixed Code
Number: 4

Filter Name: Protocol 50
Filter Type: Custom Filter
IP Protocol: Custom Protocol
Protocol Number: 50
Direction: Both
