    Hi All,

    I have 4 sites with ADSL. ( The ISP Changes the IP every 7 to 12 hours on my ADSL accounts ) I need to setup a VPN between all 4 branches.

    Whats the easiest way?. I tried to setup between the branches using 4 WRV200's but the vpn is not stable at all, I managed to get one semi working for a short period of time ( dont ask me how I just tinkered till they worked)

    Any input will be greatly apreciated.

    The easiest way is to get static ip's in your case. Because your ip's change often i dont even know if ddns is going to help. Your only other option would be to build tunnels when you need them, check the ip's, build the tunnel use it then leave it until it dies or tear it down and build it again. If you need stability for work or buisness, i would just invest the extra money for the static ip's.

    What topology are you using?

    One that might work is a star topology with the centre of the star having a fixed IP. Then the other nodes could be like "road warriors". Road warriors need to initiate the connection to the centre because they are the only ones that know their own IP and when it changes.

    RANT:

    The Openswan IPsec software used by Linksys has provisions for road warrior. In particular RSA Sig authentication. Unfortunately, Linksys disabled this feature or at least did not expose it in the GUI. Linksys even included the feature in the original manual. I'm annoyed because it was on the basis of this feature that I bought my WRV200.

    Instead, Linksys wants you to use IKE Aggressive Mode with PSK authentication for road warriors. Even though Aggressive Mode has known security weaknesses.
