I guess this would work, if you match on outgoing interface?

route-map SP_A_NAT
match interface $MY_OUTGOING_INTERFACE

ip nat inside source 155.1.5.5 155.1.13.7 route-map SP_A_NAT

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,
