How change Bind interface for ipsec tunnel

[#1]

Always in the migration of my internet link: I have a ipsec tunnel with one provider. I want change the bind interface Wan1 to Wan2 so i don' t have to rebuild ipsec phase 1 and phase 2 with the provider. But i can' t change this parameter, i try put down the tunnel in mointor screen but no response when i click on Bring down button. Maybe someone i have already do it or something like that Thank you for your help.

Hi I find the blem. When the tunnel was assigned to firewall rules, you can' t change the bind interface. It' s a normal drawback so i unassigned ipsec tunnel and change binding and after i recreate the firewall rules for the right interfaces. And i will check with provider tomorrow but i think it' s ok Have a nice day
