Hi,
By, "their public keeps changing", I assume you mean public IPs?
Here is an example as to how DDNS is configured on a router using DynDNS as the DNS service (http://www.dyndns.com/).
I haven't tried this but in theory all you then need to do in the set peer command of the crypto map is to enter the DynDNS name of the remote router.

Hello erveryone,
i have the same project Site to Site VPN with ADSL. DynDNS works fine, but the ipsec VPN Site to Site doesnt works.
I mean, configure vpn with dynamic crypto maps should be the correct way, if I implemtation the fqdn???
If I use it with static crypto maps and static ip, it works finely.
Who has an howto to configure it?
Thanks and Best Regards
Torsten

Hi,

then you need to use these : crypto isakmp identity hostname and crypto isakmp key xxxx hostname commands
