OpenVPN disable compression MR600 v3
Model: Archer MR600 V3
Hardware Version: V3
Firmware Version: Latest
Hi, I have just bought a dozen pieces MR600 for my business. After configure i download and install OpenVPN 2.6 beta from 28 December 2022 r. I noticed that OpenVPN is not working. Connects correctly (green icon) but no communication with LAN (ping and rdp not working). After a long search i found that the compression option is to blame. In future OpenVPN 2.6 compression will be disable by default and MR600 have default compression enabled in OpenVPN server.
We can`t change this settings :/ from GUI. For now to work my OpenVPN server i'm back to OpenVPN 2.5.8 and connect with comp-lzo adaptive in client config and now everything works but in future release when i update OpenVPN client to final 2.6 version it will stop working again so please in next firmware update remove compression from OpenVPN server or add in GUI options for users do enable/disable compression. In the future, the problem will affect not only me.
I also read that compression is a security risk and which is why OpenVPN team disable this option in future release.
