Hi all,
we are searching some tips or advices about vpn speed.
we try to connect 2 networks with OpenVPN in site to site connection. 1 router is a RT-AX88U (3004.388.4), the other one is an OpnSense router.
Both sites have 1Gb/s fiber connection but the bandwidth throught VPN is limited to ~40Mb/s.
We have tried hard to have successful connection but we need a better speed.
We tried a speed test with iperf. 440Mb/s with direct connection via Internet with a port forwarding. 40Mb/s throught OpenVPN.
The configuration is as follow :
Tun
UDP
Auth Mode with Static Key
KEys and certificates generated by AsusMerlin router.
HMAC : Auth SHA 256
Cipher : AES-128-CBC
Compression : LZO
Custom conf :
sndbuf 0 (also pushed)
rcvbuf 0 (also pushed)
Is someone as tips to have a better speed.
Regards
Tamo
