I am planning to deploy a VPN connection between the Head Office, couple of branch offices and Remote Access VPN.
Some of the office has Router as internet facing and others have Firewall as internet facing.
I am plannng, if all the VPN connections are terminated in one place, it would be east. I have configured several options. I thought of DMVPN initially. I guess i cant implement DMVPN on firewall and remote access VPN. Am i right..?
Then i thought about GRE/IPSec VPN. So that i could you dynamic routing protocols for routing. But again, i assume ASA / PIX will have some issues with GRE.
Could any one please suggest any suitable options for me. The main requirements are, I have routers as well as firewalls at front end. And i want to use dynamic routing protocols for routing.
