Model: ER7206 (TL-ER7206)  
Hardware Version: V1
Firmware Version: 1.4.1

I am currently using Omada SDN version: 5.13.30.8

 

I'm not exactly sure when my OpenVPN server hosted on ER7206 stopped working.

 

I can successfully connect and authenticate, but no traffic seems to work. 

Omada -> insights >VPN is showing the user is connected OK.

 

Do I need to do anything else?

Thank you Mr S for this: "to get it to work with mobile client Edit the exported OVPN file, delete the no from the string comp-lzo no" I have done this, re-imported the profile and it has solved the problem! Many thanks for the hint.

  @J4ce 
I've got the same problem from IOS and OpenVPN Connect. No errors in clients log.
Connect and traffic from PC or Mac works (latest OpenVPN Connect clients for those platforms).

 

Router:

ER605 v2.0

Firmware Version:

2.2.4 Build 20240119 Rel.44368

 

Controller:

Model OC200 1.0
Controller Version 5.13.30.20

Firmware Version 1.29.4 Build 20240304 Rel.54362

Iphone client connecting with no traffic: 13 Pro IOS version 17.4.1, OVPN Connect 3.4.2

I have exactly the same problem as "Barde" on an Omada installation (OC200/ER605 - both with latest firmware installed), following the App store update to the OpenVPN iOS client, from 3.4.1 to 3.4.2 (5723)

At the moment the Windows client version 3.4.3 (3337) still works fine..... 

 

Having had some dialogue with OpenVPN support, their conclusion is the server is pushing compression which is now thought to be a vulnerability and should be disabled on the server - see this article: https://community.openvpn.net/openvpn/wiki/Compression#

Please add a link to this thread? The screenshot is not too helpful if I need to search multiple forums to try and find it seeing there is no global search.

 

EDIT: here is the link I Found
