Im having some major issues with my new setup. I have a Cisco Router (1921ISR) that is connected to the internet through a t1. In addition to that is another cable modem. Each of these are connected to my firebox through an external interface.
My router is on the 10.1.10.X network.
My internal network is 192.168.1.X
I have several NAT statements on my router pointing to 10.1.10.X addresses. These addresses are defined on my firebox as seconday external addresses and I am SNAT'ing them to 192.168.1.X addresses on my local LAN.
This is mostly working well for everything. However, there is an FTP I am connecting to through the a VPN on the cisco that will not connect. The source is a 192.168.1.X address.
This seems like a really convoluted way to do this. Is there any easier way?
