I'm configuring stateful nat with HSRP between two routers with overload to PAT to one IP address. Is it possible to use the virtual/standby IP configured for HSRP as the IP in the nat pool statement with the overload command? For example:
router1
f0/0
10.1.1.1 255.255.255.0
ip nat outside
standby ip 10.1.1.3
standby name SNAT
standby priority 110
standby preempt
int s0/0/0
192.168.1.1 255.255.255.252
ip nat inside
ip nat Stateful id 1
redundancy SNAT
mapping-id 1
protocol udp
ip nat pool NAT 10.1.1.3 10.1.1.3 netmask 255.255.255.0
ip nat inside source list HIDE_IP pool NAT mapping-id 1 overload
router 2
f0/0
10.1.1.2 255.255.255.0
ip nat outside
standby ip 10.1.1.3
standby name SNAT
standby priority 105
standby preempt
int s0/0/0
192.168.2.1 255.255.255.252
ip nat inside
ip nat Stateful id 1
redundancy SNAT
mapping-id 1
protocol udp
ip nat pool NAT 10.1.1.3 10.1.1.3 netmask 255.255.255.0
ip nat inside source list HIDE_IP pool NAT mapping-id 1 overload
Thanks

I think it is possible. The link below has an example of using overload commands on IP nat pool in HSRP.

What about using stateful NAT with overloading the outside interface? I am not able to code the keyword "mapping-id" which would cause the active router to exchange state information with the standby. I have 3925 router. I can only code the mapping-id keyword if I am using a pool of ip addresses by which to NAT.
Please assist.

if you want to use one IP
then make the pool start and end as the same IP in this case you will be able to use the pool commands with maping-id and the IP will be used only the one you specified in the pool
by the way becareful that SNAT is end of life feature with Cisco IOS !!
hope this help
