I tried installing m0n0wall on a machine with Realtek embedded NICs.
What happened is that prior to booting, the machine's NIC is connected to
the Switch at 100mbit/full-duplex, but after booting, it becomes
10mbit/half-duplex and cannot communicate with all other machines on the
network. The ping or any other function all fails.
Hope someone might be able to help. Thanks.
