The other NIC will be wired via a crossover cable to another host on the same subnet, thus providing a full duplex (FD), 100Mbps connection, without the expense of a switch. I have seen numerous writeups of doing this as a bridge to another subnet, but none to a host on the same subnet. Desired configuration: __ 100Mbs/FD __ 100Mbs/HD __ 10 or 100Mbs/HD | |----------| |---------| |---------------> |__| fxp0|__|fxp1 |__|---------------> W95 host FreeBSD host Hub Other hosts I have attempted a similar setup with an Intel EtherExpress and an NE 2000 compatable NIC. __ 100Mbs/FD __ 10Mbs/HD __ 10 or 100Mbs/HD | |----------| |---------| |---------------> |__| fxp0|__|ed0 |__|---------------> W95 host FreeBSD host Hub Other hosts This met with limited success. The problem was only the first NIC to be ifconfig'ed could be used. An attempt to ping the second NIC from the FreeBSD host resulted in the message, "arpresolv: can't allocate llinfo for www.xxx.yyy.zzz". I could ping whichever NIC was ifconfig'ed first, but not the second. An attempt to ping the second NIC from another host would hang. I have a basic understanding of networks, how to use the route and ifconfig commands, subnetting and such, but lack the detailed knowledge (obviously) to make this work, if it is possible. I would buy a different NIC if the kernel will not support 2 NICs of the same type. Can someone help me or direct me to a source of info? I'll gladly provide any info you need about my network and hosts. Thanks, Toby To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
