UDP Work..  But with firmware 1.2.1 Build 20240123 Rel.59656 UDP work for a short time with before communication is broken VPN show connected on OpenVPN server and Omada but no traffic in VPN tunnel.

Unifi routers connected to same OpenVPN server have not this problem so problem is not OpenVPN server.

Hello,

Can someone please give an update on this.

I recently purchased an ER8411 for the purpose of its VPN capability and obviously being a reliable router to replace my ISP router.

I have tried every possible combination of (OPEN) VPN configuration, including:

Split, full, using TCP, UDP, different ports other than 1194.

I have setup using DNS, NO DNS.

For IP Pool I am using a different Pool from my main LAN (is this correct?)

I probably spend couple of day to test every possible combination without success!

I can connect using my phone and get a IP form the Pool, but no internet and no LAN access!!!

Am I doing something wrong or the VPN Client is completely broken on the ER8411?

Can someone please confirm if the ER8411v1_un_1.2.1_20240123(Beta) Firmware would work?

If not, is there an firmware update coming soon to fix this issue?

ER8411 V1.0 Firmware 1.2.0

Thanks.

you probably have a completely different problem to what I'm struggling with, look at this link and I think you'll get openvpn working.

Oh man, thank you so much!!!

I was pulling my hair on this issue.

That tweak solved the no traffic issue on my phone, however for some reason I cannot block people from accessing my main LAN when they are connected with "Tunnel Mode: Full" even my ACL is completely blocking the VPN LAN POOL (192.168.10.1/24) from my main LAN (192.168.1.1/24)!!!

Thanks again!

maybe you should try SSL, there are more configuration options.

you use the same openvpn client when you use SSL

Thanks for the suggestion, will give it a try!
