I've got a Linksys Rv042 at a remote site, connected to a standard DSL service (dynamic public IP address) and I've got that RV042 setup to do Dynamic DNS and to also do an IPSec VPN back to my main office which is running an 2821 on a static public ip address. I've got the vpn setup and working between these two devices, but whenever the IP address at the remote site (RV042) changes, the VPN has to be reconfigured on the 2821 (really just the 'set peer' field in the crypto map)....is there anyway to have the 2821 use the dynamic dns name rather than the ip address? I've tried the 'set peer name' in the crypto map, but it does a dns lookup immediately and then populates set peer with the current ip, and then never looks up that name again. Is there any way to do this? Thanks.
