Thank for reply,
m0n0wall 1.3x is based on FreeBSD 6. There is site with supported NICs by freebsd 6.0:
http://www.freebsd.org/releases/6.0R/hardware-i386.html#ETHERNETThe em(4) driver supports Gigabit Ethernet adapters based on the Intel 82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546, 82546EB, 82546GB, 82547 and 82573 controller chips:
Intel PRO/1000 CT Network Connection (82547)I found problem: Intel PRO/1000 CT Network Connection (82547) is not the same as Intel Gigabit CT Desktop Adapter (82574L) and it not supported by freebsd 6.x, only 8.2 (core of m0n0wall 1.8.x).
By the way, when new ver. 1.8.x of m0n0 will be released?
