recently i set up a dmvpn installation with a few spokes.
Unfortunately we found out that all spokes are within one ISPs Network and the ISP does PAT with one Outside Global IP Address
for all Spokes. I know that this scenario is unsupported by DMVPN, but does anybody know a workaround for this issue?
We are using 2811 as Hubs and as Spokes with 12.4T(20)
Your Help is very much appreciated.
