Hi Will,
Thanks for the answer,
1&2 perfect, I wasn’t sure the backup was a full backup as it stated: “of the current configuration files”
3, this post for example (or the one you mention), but as I am on the openwrt 21.02 and firmware 4.8.2 I wasn’t sure it was the same.
If it’s ok perfect for me, I can delay my update to 24.x and find a way to connect the new ssid1 to vpn server 1, and the new ssid2 to vpn server 2.
4.I won’t be able to test this until I got a “real” connection, I’ll check the doc in the meantime.
Thanks for your time!
