man ifconfig - not the 'mtu' option. You should set the MTU size on the interface to match the uplink MTU. And you should make sure you handle ICMP need-frag error messages, otherwise Path MTU discovery will be broken. Only use the net/tcpmssd? That's a workaround for not properly handling ICMP error messages, and just for TCP ;-) > Will it be possible to process both two channels of 1Gb? > > Never. ;-) Not in practice. What is the bandwidth - delay product? That's a fraction of the 1Gbps you'll never get. - M _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
