Hello everyone. At remote branches, we change the ISP, now we need to change the public IP addresses, how to smoothly configure the replacement of the BOVPN Gateway IP address?
If you temporarily have 2 active ISP connections at the branch, and you have an unused firewall interface, then you can set up a failover BOVPN.
Then you can disconnect the old ISP connection, and the BOVPN should fail over to the new ISP connection nicely.
