How to configure IPSec VPN tunnels where the remote endpoint has a dynamic public IP address?
Posted by Gabriel Yu on 02 April 2008 03:28 AM
The Vigor 3300 models use the same list of profiles for LAN-to-LAN and host-to-LAN (teleworker) VPNs. There are however a subtle difference depending on whether the other endpoint has a static or dynamic IP address:
  • Where the other endpoint has a static IP address, you can assign a different pre-share key in each Vigor 3300 VPN profile,
  • Where the other endpoint has a dynamic IP address you must:
    • enter Security gateway 0.0.0.0
    • all can only share one pre-share key; which means that ;each Vigor 3300 VPN profile for dynamic client must have the same pre-share key.
