SNAT exemption

Hi guys, I am using SNAT on a cisco router to accommodate HSRP redundancy.

My config is:

ip nat pool SNATp netmask
ip nat inside source route-map SNAT pool SNATp mapping-id 50 overload

On the standby HSRP router, I cannot communicate with the primary as the primary holds the .2 ip address, and due to the SNAT config, any traffic leaving the standby will also have the .2 address. How can I ensure that SNAT is exempt or ignored when .4 talks to .2 and .3 and .3 talks to .2 and .4

Hope that makes sense.

You should be able to do a deny in your route map for the IPs you do not want to SNAT.

In your access list for the route-map match statement, put a deny statement first to deny the IPs you do NOT want SNATed.
