Title: OpenVPN Bad LZO decompression
Post by: bzero on February 12, 2019, 04:08:13 am

Hello,

I am trying to establish openvpn to a linux box, and get Bad LZO decompression.
I tried to disable/enable LZO option on opnsense, but still getting issue.

Please share how to fix it.
Thank you.

I've been trying to disable compression on the OPNsense server but I don't think the GUI option works - in the end I visited https://community.openvpn.net/openvpn/wiki/VORACLE (https://community.openvpn.net/openvpn/wiki/VORACLE) (under Mitigation) and added to the following to the custom options:

Code: [Select]

--compress stub-v2
--push "compress stub-v2"

Seems to work for me and disabling compression on OpenVPN for Android allows the connection to work - before it simply blocked traffic.


Does anyone know where the OpenVPN server config file is as I cannot find it and want to check what the GUI changes?
