Configure a server's WAN (exit) IP?

Brook Powers
Beginner
Beginner

We have cable internet with 5 assigned static IP addresses.

The UC-540 is assigned say 8.8.8.10

Our SBS 2011 server is assigned 8.8.8.11 with ports 25/80/443/3389 NAT'd to 92.168.10.10 on the LAN

All server (192.168.1.10) traffic must exit the network via 8.8.8.11 in order to eliminate multiple issues (email, vpn, etc).

Currently when I point the server's browser at http://whatismyip.com, the website returns the UC540 gateway IP of 8.8.8.10 in my example.

I need the website to return 8.8.8.11 instead.

Any help appreciated.

Hello,

My apologies, I didn't provide you the correct instructions.

You first need to define the pool of available external IP addresses to use. In this case, just the 1 external IP for the server.

Then you need to create the NAT mapping where you tie the internal and external IPs. Make sure to set the NAT mapping for all ports.

Thanks,

Hello,

You can do this in CCA under: Configure -> Security -> NAT. Then you need to define a NAT pool with the external IP and internal IP.

Thanks,

Ive taken you advise and deleted, receated, restarted and still the same result.

Any ideas?

John,

That worked. Thanks much.

The secret is to delete all the pools.

Then, create the new pools.

Finally to create the proper NAT mapping.

It may have helped to wr and restart the UC540 as well.

Cisco should make CCA apply in changes in the correct order in the next relase.
