How do I set up a NAT from a secondary WAN IP

I have a UC520 and have 1 public IP and on WAN(FastEthernet 0/0)

I have now  added a se condary IP on the same wan and it shows up like this

interface FastEthernet0/0
description WAN
ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy secondary
ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy

I added a NAT rule to WAN to go to an inside IP but it wont work.

I pinged the WAN secondary IP and i get no response

I am unsure what to do next.

Please help me

Re: How do I set up a NAT from a secondary WAN IP

Here is what you need to do:

1. Configure these additional IP as secondary WAN IP.


interface FastEthernet 0/0
   ip address A.B.C.D 255.255.255.248 secondary

2. Create the static entry

ip nat inside source static ip 192.168.1.61 A.B.D.C extendable

3. this may not be necessary since there is no access-list in his WAN interface (FastEthernet 0/0)

access-list 104 permit ip any host A.B.C.D
