First I'm almost certain this is a cable modem/provider problem. We have
a 20mb ethernet circuit that works fine with the same pfSense.
We upgraded to a 100/10mb cable modem, when we put this on the WAN of
the pfsense, we are getting major packet loss during peak times, and
speed test sites that won't even load. Non-peak times we get no packet
loss, good speed tests (50+mb)
The problem I'm having is that when we take the pfSense out and plug a
PC directly into the cable modem, the speedtests look fine and the
dropped packets go away. Both during peak times and non-peak.
My thought is the number of packets going over the cable modem with the
pfSense is a lot greater then just one PC doing a speedtest, and the
cable modem can't handle it. We have about 100 clients behind the
pfSense trying to access the internet during peak times. The traffic
graphs on pfSense only indicate we are doing 5-10mbs download and 1-5
upload, so we are no where near maxing out the cable modem bandwidth wise.
I've checked wan ethernet settings 1gig full duplex, no collisions or
errors on the pfSense side. I don't see any problems in the log, we are
not doing any traffic shaping.
The cable modem provider says if you plug a PC into the modem and you
get a good speed test, then it's your firewall. I tend to agree with
him, but the firewall works fine with the 20mb Ethernet circuit, and it
also works fine during non-peak times when not many users are on.
Has anyone run into a problem like this before, or have any tips to
prove what could be the problem.
Thanks,
Adam
