I am trying to make a site-to-site VPN between our office and the boss' home. They both have ADSL with dynamic IP addresses. The office uses Cisco 877w router. At home is the Draytek 2800.
Has anyone had experience with these devices? I don't know if VPN between them is possible as they are all dynamic IPs. We use a DynDNS on the Cisco side, and set the Draytek to use URL to work out the IP. Could someone please let me know how to setup in the Cisco end? We have the Cisco setup for remote login only. I am thinking of Easy VPN.
Also at the Draytek end, we will put in a VoIP handset to connect back to the server in the office. The VPN should be always on because the handset will look for a DHCP server.
I attached the Cisco config. Thank you very much for all comments.
