      Hi,

      yes, when i use my onboard interface as WAN on PfSense i am able to ping 192.168.2.1.

      When i use my USB LAN interface on PfSense the clients recieve an IP-Adresse and the DNS entry points to pfsense (192.168.1.1).

      I tried both on pfsense. Resolver and Forwarder, but it did not make any differences.

      In the meantime i have an additional information: my USB LAN device has a AX88772C chipset, which is not supported by FREEBSD. The last AX88772 version, which is support is AX88772B.

          I really don't get why anyone would use a usb nic for anything than maybe an OLD school laptop that had no nic, or the lan onboard died, etc..

          Why anyone would attempt to use a usb nic for any sort of router/firewall just make no sense to me..  You have multiple pieces of hardware and you want to run special distro as your router/firewall - so cleary your beyond the $20 soho router users.  But you can not afford a $10 nic to put in your machine or for that matter some $100 hardware to run your pfsense on?

            Hi,

            i have a system with only one LAN interface. The system has a very low power consumption and is working very well. I decided to use it as a test platform for PfSense before I decide to buy a "bigger solution". Just wanted to check out if it fullfills my requiremets.

              Hi,

              I am still trying to get a usb lan dongle working - somehow. I bought a new one, which is definitly supported by FreeBSD (ASIX AX 88772). I am expieriencing the same problem, but in the console i have a new message: arprequest: cannot find matching adress.

              Somebody an idea?

                Start a new thread since your current problem has nothing to do with your last one.

                  I'm not sure if there is a connection between those two topics or not.

                    "arprequest: cannot find matching adress."

                    For what address?  Why don't you just get a REAL nic??

                        I can confirm that there are some serious issues with USB ethernet adapters.
                        I also tested the above mentioned ASIX AX 88772 and had the same problems as the thread opener: pings to IPs do always work, DNS lookups do never work and standard TCP transfers do work sometimes.
                        If, with the same config, I replace the USB by a PCI card, everything works fine.

                        The reason why i did this: USB card is 9€, low profile PCI card + 90° riser card for this case is 55€, but the time I spent working on this problem is worth way more…

                        If you want to see some serious shit, look at the attached Wireshark capture. This was captured on my home router (192.168.66.2), with 192.168.66.21 being a windows machine making a reference lookup and 192.168.66.199 being the USB-WAN interface of the pfSense machine in question. Don't ask me why I don't get any query responses (but two) to the pfSense machine's requests...
