Off Topic, Related • Re: Bad LZO decompression header byte: 0

Hello,

I was able to find a solution for the compression error.
My VPN goes through two routers interconnected by Wireguard, the 1st router seems to poorly transfer packets to the 2nd router via the VPN.
Because when I disabled compression I had other errors.

To solve the problem I put a low value in the tunnel MTU.
So I removed the options: mssfix and fragment 1500. To replace them with: tun-mtu 1300.

The router still has: iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
to maximize outgoing packets...

So I no longer have any compression problems.

However, be careful with LZO compression, see:
