Hi all,

i would like to setup 2 public ip address on wan interface (cisco 870 wan int. = fa4). The first IP for NAT overloading from user VLAN and the second IP for email server and web server. Is there any chance for binding two IP on interface fa4?

Thanks for your reply.

Instead of having a secondry address on the WAN , create a loopback address and do a pat with that for ur email server and webserver .

Hope this helps

In addition to Vanesh's comments make sure that you have your routing set at the SP end for your loopback ip via the WAN ip otherwise the reachability wont be there to the secondary ip address..
