L2TP VPN not working on IoS with DDNS?
Hi.
I just got DDNS for my business dynamic IP. Everything work flawless as before exept one thing.
None of my Apple devices can connect to L2TP anymore... How can this be when the windows computer connects (with built in VPN client in Win 11) without issue on the same L2TP setup? Is it not possible for ios devices to connect to L2TP with DDNS? I even ran the Wizard and created a fresh L2TP config but with the new DDNS name. Everything else like passwords, key types is exactly the same as before i had DDNS.
I have a USG FLEX 100, firmware V5.31(ABWC.0)
I have no clue what casuses the problem.

After i changed from DNS to IP4v (0.0.0.0) the ios devices started connection again. I was fooled by the Wizard once more0
