Hi Experts,

Wonder if someone could help me?

I need to setup a Cisco to Cisco VPN on 2x Cisco 2921 Routers Both running 15.1 IOS.  Problem i have is I dont have a Static IP, both ends are Dynamic.

Is this possible with DMVPN/IPSEC?

The Problem i have setting it up is:-

interface Tunnel0
 ip nhrp map 10.1.1.1 90.26.32.11 - I can only seem to choose a IP Address and not a hostname?

I really need to do something like:

interface Tunnel0
 ip nhrp map 10.1.1.1 90.26.32.11 vpn.domain.com

I have read a few things now but some people are saying it is possible, some are saying it is not. I cant seem to find any example for Dynamic at both ends though.

Many Thanks for any Help in Advance
TME
