Hi, I've had a search around but I've not found a conclusive answer...so:
We would like to connect two offices with ISA 2006. One/main office has a fixed (static) IP and the other/branch office as a dynamic IP, but we are using DynDNS. Question: is it possible to create a branch office VPN connection in this scenario? We have a number of roaming users that connect to the main office over VPN (using IPSec and certificates) successfully.

hi, We have similer setup & we have succesfully established the Site-to site VPN accross the sites even without using DynDNS. Usually , when branch shuts down for any reason, they get new IP every time when it comes up, but the STS connection is established, because HQ has Fixed IP. When you want to connect to branch ( usually not required) , you just ask them the current external IP they have optained & update the same in Remote site connection at HQ ISA ....so you get connected. external ip can be optained by visiting http://www.dnsstuff.com or by so many other ways. if you require more help on this please mail me at firstname.lastname@example.org or post it here.
