I have a Cisco 1721 as my Internet router. It is configured with access-lists to pre-filter Internet traffic,and NAT. I need to setup MUPVN on a Firebox Soho6tc, but need to first allow the traffic through the Cisco router.
What protocols and ports need to be open on the Cisco router to connect to the Firebox?
Is this possible without turning NAT off on the Cisco router?
Thank you very much.
