I am trying to set up VPN GW-GW between C857 and C877. One of the sites has fixed IP, but the other one has dinamic IP assigned by ISP. If I use IPs when setting up ipsec tunnel with preshared keys, I find no problems, but if I use hostname for one of the sites, taking advantage of Dynamic DNS, vpn cant be established, with an error of key missmatch in the side where I use hostname.
I configure hostname in:
crypto isakmp key "key" hostname "hostnme"
Cryptomap: set peer "hostname"
Do I have to use for this situation with dynamic IPs certificates?
