Check and see if your router supports the command ?tunnel mode gre multipoint? and that your tunnel supports commands that start with ?ip nhrp ?.

Even if you have a dynamic DNS service set up (I am using duckdns.org <http://duckdns.org/>'s service happily for a while now if you need one), I don't know if Cisco IOS does a DNS lookup every time it loses a GRE connection to the destination, or even if a destination can be a domain name instead of an IP address. There are fabulous GRE experts in this group who might chime in. >> > > >> > > If the answer to all of the above is yes, and you are willing to move to area 31, I can give you a GRE tunnel end point on Area 31. >> > > >> > > The other alternative is a MULTINET connection to area 31 which also I can provide if you wish.
