      Hi all,

      I get this collisions on my LAN side. The numbers increase all the time. I am thinking it must be because of duplex mismatch. Pfsense auto selected automatically. What do you think could be the problem.

      LAN interface (bce0)
      Status up
      MAC address 00:1a:a0:1e:e7:5b
      IP address 153.189.5.100 
      Subnet mask 255.255.255.0
      Media 10baseT/UTP <half-duplex>In/out packets 864781/872813 (118.62 MB/617.22 MB)
      In/out errors 0/0
      Collisions 135458</half-duplex>

        You do have a switch in front of the pfsense and not a hub, don't you?

          I'm guessing a hub, based on this:

          Media    10baseT/UTP<half-duplex></half-duplex>

          If that's a hub, collisions are par for the course.

          If that's really a 100Mbit switch, then you have a card, cabling, or port issue.

            I have a switch in the front. I think I should change the 10 MB to 100 MB, Pfsense automatically selected it so I did not bother.

            Thanks for your suggestion guys. I will play with this.

              Do not play. Just set up the port on the switch to auto-negotiate. This is the only correct setting unless you want to set up speed/duplex on pfSense.
