Hi previously i had 40-50Mb/s in upload with Wireguard with MTU 1372 in WG interface but it seems since update it's max 10Mb/s

What happened? is it the same for you?

Best regards

PS: i tried with MSS in lan but the same result
cf:
https://forum.opnsense.org/index.php?topic=21184.0

I get about 20 MByte/s and I have clamped MSS at 1360 for the Wireguard Group under Firewall->Settings-> Normalization, as this prevents other problems as well.

For reference: I have PPPoE over 802.1q running for the WAN connection.

Thx a lot for have take the time to answer me, i'm not sure about the result for my connexion i need to test it more only MTU, only MSS and both

Best regards

For Win10 I found MTU = 1372 best working. With default I also got very very low speeds.

Try

Code Select Expand


[Interface]
MTU = 1372
in client config.

Hi thx a lot it's much better now it's 25-30Mo/s
Any recommandation for Android?

Best regards

Hi, I can't d/l faster than 5Mo/s using Wireguard (Samba and FTP same) while the server bandwith upload is about 560Mbps (70Mo/s) and d/l on the client is about 800Mbps.
Both PC are under Windows 10, the client use Wireguard client for connect while Opnsense is the VPN server

It seems normal to you? if not what must i check?

Best Regards

[D/L: 115Mb/s ????U/L: 600Mb/s ????]

Hi, i don't understand Speed test results:

Site A: Opnsense is Wireguard server.
Fiber 1Gb/s d/l and 700Mb/s U/L theorical (but in test it's about D/l: 800Mb/s, U/L 300Mb/s)

Site B: Opnsense but i use Wireguard windows client.
About same connexion speedtest result than A

When the VPN is up, on Lan Site A, launching via VNC speedtest (traffic is outside the VPN):
Result about:
D/L: 115Mb/s ????
U/L: 600Mb/s ????
If i close the VPN and connect via Teamviewer: speedtest comeback to normal value (D/l: 800Mb/s, U/L 300Mb/s)

On the client (checked ip it's his own external ip so it's outside the VPN)
It's about same result than without the VPN:
D/l: 800Mb/s, U/L 300Mb/s

And Traffic in the VPN:
D/l from: A to B
It's trottling from 6 to 18Mo/s (average seems 10Mo/s)
U/L from B to A
It's trottling from 3 to Max 14Mo/s (average seems 5Mo/s)


Why when the tunnel is up the D/L test on speedtest (so outside the VPN give only 115Mb/s and U/L the huge 600Mb/s on server?
It does the same for you?


And about bandwith in the VPN is it normal result for 1Gb connexion?

Thx for help to understand certainly something wrong in my config but i don't know what?

Best regards

Hi,
Thx a lot

Best regards

Hi Opnsense is new for me, I'm trying to do the same, first Roadwarrior and next step must be s2s.
I get Roadwarrior (Android) working it seems the internet traffic come in the smartphone by WireGuard.
1: But i can't get traffic to the lan, what i maked wrong?
2: I didn't understood what was the solution for your s2s?

3: on Android how have only lan traffic by WG and no internet traffic (I mean internet outside Wireguard)

Sorry for my bad english

Best regards
