Could you use a static IP rather than using DHCP and see whether that makes any difference?(Note, you have to revert your changes made to axe(4) before trying that). Also show me the output of 'ifconfig ue0' before/after running dhclient(8). Apart from what I originally described... Networking does work, but not when packets pass through ipfw and nat. If I add my ipfw rules before the divert natd rule networking works as expected, without the SYN,ACK response packets are not accepted if I e.g. connect to something on the axe interface. I have validated the ipfw ruleset with the onboard realtek NIC and it then works as expected. # usbconfig -u 3 -a 2 dump_info ugen3.2: product 0x772b vendor 0x0b95 at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (200mA) Kind regards, Spil.
