@Enmanuelrp30 ok, so you use OpenVPN, unfortunately TP-Link aren't that good at OpenVPN, there's a lot of weirdness there.. unfortunately it's not possible to use fqdn on OpenVPN. you can use it on...

@Enmanuelrp30 do you have a screen shot of your vpn config? are we talking site to site vpn is config like that, and have always been, notting new now

Please make Wireguard more user friendly, it must be possible to export the Wireguard config file.

Please add batch add on IP Port group and IP Group. Reading in from a file is easier than entering the IP manually in the IP port group or IP group for each site that needs the same settings

Please update OpenVPN now it only works between TP-Link devices and old servers with OpenVPN 2.4 or older. Also add Policy Route to OpenVPN tunnel.

@pwnjuice try downgrading to version 2.1.4 the version 2.2.0 you are using was withdrawn because it had too many bugs, You find 2.1.4 in this thread...
