we are running a lan-to-lan vpn with freeswan and dynamic ip adresses on both sides. it works, but you have to restart the tunnels on both ends if one end goes down. We are using a small script run by cron on both gateways which is pinging into the remote lan to see if the tunnel is still existing and taking action if not.

Hi list,

I'd like to connect a remote Win2K box to a internal LAN which has only a dynamic IP via DSL. I allready have dyndns.org domain, that gets updated on DSL login.

Now I glimpsed at free-swan's documentation and - as far as I understand

• the setup-guide says I needed fixed IPs und update the DNS with key

info and so on. So it is not possible for me to use it ?

I currently have:

• SuSE 8.2 and the provided freeswan 1.99 on the gateway
• Win2K SP4 on the outside boxes

Later there should be 2 Linux gateways connecting 2 LANs but still dynamic IPs.

Is there someone who could point me to a HowTo or at least verify that what I'd like to do is possible with free-swan ?
