Hi, I'm having a little trouble figuring out how to do this, or even if it can be done.
When we originally got our t1 installed, we ordered 5 public IP addresses. At the time, this seemed like enough, all we needed was smtp, www, and a couple of other things.
Now it turns out we need more public ip addresses for ftp, more www, etc.
Our ISP could not expand our existing subnet. Instead, they offered us 5 more ip addresses in a non-contiguous subnet.
For example:
Original subnet: 62.43.171.2 through 62.43.171.6 (255.255.255.248)
Additional subnet: 62.43.171.242 through 62.43.171.246 (255.255.255.248)
The way I envision this working is to put a secondary ip address on my router's outside interface:
Router#(conf-int): ip address 62.43.171.242 255.255.255.248 secondary.
But I'm not sure what the routing statement should be. Currently the default is set to:
0.0.0.0 --> 62.43.171.1If I add a route statement: 62.43.171.241 --> 62.43.171.242, will that work to route traffic to/from this new subnet?
Thanks.
