We are trying to optimize our network set up, and would like to give our vpn concentrator a public ip.
Our ISP has given us a serial ip address of (ip address made up, but last 2 octets are real) 18.104.22.168 which is currently going to our cisco 2811 router.
We have a public ip address range of 22.214.171.124-126
We would like to give the vpn concentrator a public ip of 126.96.36.199
There is an hwic on the 2811 router which has 4 open switch ports.
I ran a cable from one of these ports on the router to the vpn concentrator, but I don't know what gateway to tell the concentrator to use since the serial ip is not on the same subnet as our public ip range.
Is there an optimal way to do this?
