Firmware 384.3 - is Nat Loopback buggy?

[Matej]

Hello,

I have a question about connection issues with my openvpn server since I updated my routers to the new 384.3 firmware.

I have three houses that are connected through TAP Openvpn. All three houses have an RT-AC68U router. Each network has an Intel Nuc with openvpn software and a dedicated DHCP address pool range. So, one server and two clients.

Since I updated to 384.3 my two clients cannot connect to my openvpn server anymore.

I tried to disable the routers firewall and the clients were finally able to connect to my server. Since I need the routers firewall to be enabled, I re-enabled it and both my clients were disconnected.

So, I tried to enable the firewall and set to DISABLE NAT LOOPBACK and both my clients were able to connect to my server.

Is this normal or is there a bug into the 384.3 firmware?

Thanks

In my recent experience with RT-AC68U and 384.3 firmware, I might guess that the whole firmware is buggy.

Since I've updated to this firmware version, my router stopped working properly. The Wifi signal was right but there was a lot of lost packages and poor network transfer quality. The internet connection was terribly slow (both with single and Dual Wan). I could not stablish a connection with open VPN, but pptp worked.
I even found that the web admin page took a lot to load (as oposed to v380.69).

I ended up downgrading the firmware and everything works fine now.

You did not say whether this was the Asus loopback or the Merlin loopback. I would try the Asus loopback.

If it still does not work I would go to the admin page and do a factory "initialize" and then manually type in your settings. do NOT reload from a saved config. After that let the forum know if it is still not working. Just my thoughts.
