Title: VERY slow speeds with OPNsense
Post by: Gargamel on October 12, 2017, 04:20:36 pm
Hi, i just installed OPNSense, and ran update to the latest updates as of today.
when i check my speed at http://www.dslreports.com/speedtest i only get 24 megabits/s down and 70 megabits/s up, and i have 250/250 connection, i have checked my switch for my lan, it reports Gbit connection for all connected cables, and opnsense reports nearly no traffic on wan.

I have yet setup openvpn connection and such i would like.

I have tried to enable the 3 offloading hardware settings, rebooted, still same roughly speed.

the opnsense is nearly 100% default from installation, only changes is that i dont use 192.168 but 10.200.x.x for my lan.

what settings should i check? When i was directly connected to the box, i got full speed.
any ideas? Switch is Netgeat GS108E and everything is connected exactly as it was with pfSense.

Interfaces - Overview - WAN

full-duplex?

What means connected directly to the box?

Ah, and OPNsense is behind the OpenVPN box? Can you try lowering the MTU?

no openvpn involved.

opnsense <-> WAN /Internet

Do a packet capture on the wan, rerun Test and Upload the file

I changed the switch closest to the opnsense firewall, and now i see  almost 240/240 Mbps on all different speedtests i am using.
So it seems to be the switch fault.
