[c-nsp] site2site VPN with a dynamic IP

[Arie Vayner (avayner)]

Hi,

I guess you have only one side of the VPN using a dynamic IP, while the
hub site is a pre-defined IP address. Right?

For this you can take a look at Easy VPN (EzVPN)

Another option could be DMVPN:

(you can disable branch to branch direct communication by tweaking the
NHRP config)

Hello c-nsp,
How can I setup cisco devices (preferably IOS) to establish a site2site
IPSec VPN with one endpoint on a dynamic IP?
I prefer using pre-shared key, but any idea is welcome.

Regards.
