I'm not really sure about this, here is the output of ifconfig related to the external interface : root@charon:/root# ifconfig -m fxp0 fxp0: flags=8843 mtu 1500 inet xxx.xxx.191.100 netmask 0xfffffff0 broadcast xxx.xxx.191.111 inet xxx.xxx.191.101 netmask 0xffffffff broadcast xxx.xxx.191.101 ether 00:e0:81:23:c5:32 media: Ethernet autoselect (10baseT/UTP) status: active supported media: media autoselect media 100baseTX mediaopt full-duplex media 100baseTX media 10baseT/UTP mediaopt full-duplex media 10baseT/UTP media 100baseTX mediaopt hw-loopback It seems that fxp(4) supports full-duplex but that it is currently disabled, and I guess this is because the other end of the wire doesn't support it, since the media has been autoselected? Please correct me as I have never played a lot with ifconfig except for basic configutarion. I wouldn't be too eager to do tests with this setting since this is a production server and I have no direct physical access to it, so shutting down the only interface by mistake is *not* an option ;-) But if I was to change it, how would I go about this without shutting down fxp0? 'ifconfig fxp0 media 10baseT/UTP mediaopt full-duplex' ??
