[c-nsp] NAt issue - two isp connections, need to nat 2nd isp for two dest addresses only

[Dikkema, Michael (Business Technology)]

I think you can use route maps with NAT to do this.

Ip nat inside source route-map voice int X overload
Ip nat inside source route-map notvoice int Y overload

Configure the route-maps to match on ACLs for the voice / not voice as needed.

Make sure you route those 2 IPs to the proper gateway as well.

Subject: [c-nsp] NAt issue - two isp connections, need to nat 2nd isp for two dest addresses only

I have a generic nat overload statement that nats all my internal (192.168.1.x) traffic outbound. Works fine. I just added a second dedicated isp connection for voip traffic only and I need to have traffic destined for the two provider voip servers use the second/new ISP connection and perform nat using the public ip address of this new isp connection.

ex:
192.168.1.0 -> use isp1 connection with nat outside and nat inside statements using standard nat overload command, except:

anything destined for 5.5.5.5 and 5.5.5.6 must use the second isp connection and nat accordingly.

How do I accomplish this? Could someone provide a config snippet? Any help would be greatly appreciated.

Thank you,
