How do I set up a site-to-site VPN between 2-6 sites, when all the peers are using dynamic IP? DynDNS (or equivalent) is set up on all sites, so accessing the IP from outside shouldn't be a problem. I'm guessing using pre-shared keys isn't a problem, because it's so few peers. I do however want a full mesh network.
I'm going to buy new equipment for all sites.
Is it possible to use a DNS name as the peer (I've only used static IP)?
