Remove a VPN Tunnel

Hi,

I 'simply' need to remove a VPN tunnel from my SSG 140 firewall.

When I go to the VPN>Auto Key and hit rrmove on the tunnel I need to delete, I get the following message...

This VPN has tunnel interface binding. Please remove the binding first.

I've tried going and unbinding the interface but it;s alerady ser to none.

I'm, really stuck, don't want to remove anything that will break existing tunnels.

Any help will be greatly apprecuiated.

PS. Don;t ask me to go into the CLI, I'm not that confodent with the CLI and worry I'll break something else.

Manuy Thanks,
