DMVPN behind NAT

Unanswered Question
Nov 14th, 2007

Hi,

I'm having a little trouble getting a DMVPN up using a host that is behind a NAT device. It looks as though with my version of IOS i need to use IPSec tunnel mode, but the NHRP registeration on the hub shows the Real address of the spoke and not the NAT'd address. Because of this the spoke can't be seen by any others.

Any idea's where i may be going wrong here?

Thanks in advance for your help!

Andy

I have this problem too.

DMVPN is supported behind NAT. This is usually seen on routers. Upgrade the router software to12.3(11)T6 or greater to fix this issue.
