Hello i have a couple of 3925E routers running HSRP both internaly and externaly.
I cant get them to NAT the traffic though. They just route it out.
I also tried to connect via VPN to se if that worked and it didnt.
Im poundering where im going wrong with this.
Here is the relevant config.

Iam not sure if nat inside and outside will work using same interface with sub-interfaces !!
You can try to use NAT on stick and see if dose fix your issue

Hello.
Tried some more things.
When i change so that i have one adress in the dynamic pool that matches the Virtual ip of the HSRP cluster it seems that my NAT starts to work.
Seems that i cannot translate to different adresses dynamicly when using HSRP? Someone recognise this issue?
