Why was it set to 2? It must've been deliberately set to 2 on your system, and changing it to 1 will probably break something. >> >> Thanks! > > Hi Alan, > > did not work :( > > It also happens the errors below when I try to add a host in the arp table: > > # arp -an|grep 187.xxx > ?

It also might be helpful to see the output of "netstat -rn" and "setfib 1 netstat -rn". One guess as to your problem would be that your subnet mask is configured wrong, or that other hosts on your vlan are configured with a different subnet mask or even an entirely different network prefix. > > Thanks and best regards > > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
