Two publics IPs, one ADSL interface

I've two public IPs from my ISP. I'd like to implement them in a router Cisco 1701. First IP works OK, but the secondary doesn't. This is the WAN interface config:

interface ATM0.1 point-to-point

description $FW_OUTSIDE$

ip address 80.44.47.220 255.255.255.0 secondary

ip address 223.58.221.212 255.255.255.0

ip access-group 105 in

no ip redirects

no ip unreachables

no ip proxy-arp

ip nat outside

pvc 8/32

encapsulation aal5snap

I don't know if this is the correct config, or maybe I have to define a ATM0.2 interface

Any ideas? Thanks

Hello,

are both public IP addresses from the same provider ? Can you post the full configuration of your router ? Also, do you want to have your internal addresses translated to both public IP addresses ?

Yes, both public IP addresses are from the same provider (same VPI/VCI)

I bought two public IPs due to I've two Internet services (Citrix and secure webmail) running on the same port and different internal IPs.

Internet is reached without problems from internal addresses, and I've redirected both public IPs to internal IPs, but only one public IP (the primary) works

Attached to this post is the router config

Regards,

Cesar
