Hello,
I was wondering if it's possible on a 1720 to alias an ip on the serial
interface, so that I'd have 2 public ip's, 1 ip for each domain behind the
router?
------------ | |
internal nic | | |cisco | 101.x.x.1
-------------| FW-1 | outside nic e0/0 |7000 |-------s0/1----|
| |------>---------------- | |: |----------t1
------------ | |-------- s0/7---|
101.x.x.2 - aliased ip
101.x.x.1 would be directed to abc.co via the firewall
101.x.x.2 would be directed to someotherdomain.net via the firewall
So that the webpages, and email could be hosted on 2 separate machines.
thanks

your diagram was all messed up because of html conversion.
You should be able to do this with nat.
create a static nat like this :
ip nat inside source static tcp x.x.x.x 80 p.p.p.p 80
ip nat inside source stattic tcp y.y.y.y 25 p.p.p.p 25
p.p.p.p is your public address which will be translated to 2 different addresses.
x.x.x.x for web traffic and y.y.y.y for email traffic.
This could also be done on the firewall I believe.

that would give me 2 different servers 1 for email, 1 for web...I want 2 different domains. each domain has it's own web, and email...so
abc.com has web, and email services on this server
otherco.net has web and email services on this other server
I want each domain to have it's own public ip, so is it possible to alias a second ip on the serial interface?
