Add a second NIC to copy files between networks via IP only

By g0ldeneye ·
Hello,

My building has two internet connections, fiber and Comcast.

I have a computer plugged into the Comcast and assigned a public IP to it. I copy files from this computer to a server behind a firewall on the fiber, in the same building. The transfer rate is very low and I was wondering if I could just add a 2nd NIC to each server, assign the NICS a new network 192.168.123.x / 255.255.255.0 and don't assign a gateway to either NIC. I'd also make the metric very high so traffic doesn't default to these NICS. Then, when I want to copy data from the computer on the Comcast to the computer behind the firewall, I would just copy it via UNC using the 192.168.123.x IP addresses.

Is this a huge security hole or would this be ok?

The computer on the Comcast net would have it's firewall configured on the NIC and only allow SSH in/out.

Apparently there is one comment already, so I tried logging in to see the comment, forgot my password, reset password, now leaving this comment to see if my "comment count" goes to two, or, at least shows this comment. Maybe my initial question is considered a "comment"?
