Changing Customer Gateway Address on a VPN connection

VPN
1

I have an established VPN connection I want to move to a different IP address on my on-prem gateway. I’ve tried to find some way to change the address without recreating the entire configuration without luck. Is it even possible?

You’re out of luck. The VPN is immutable.

However, there is not much to recreate. Create a new VPN, get the preshared key.

Migrate your gateway to the new IP, and update the existing tunnel with the AWS IP and the new preshared key. Tunnel should go up automagically, and now all that remains is to update the subnet route tables to the correct VPN connection.

Thanks, I was afraid of that.

Thanks, I’ve used these for initial setup, but I’m looking for a way to change a single parameter without redoing the entire configuration.
