When configuring 2 VLANs to be on the same subnet, only one works.

I'm testing a NIC driver. I use 2 directly connected FreeBSD-7.0 hosts. When I create 2 VLANs for the same interface (mtnic0), on each host, and configure the VLANs on each host to be on the same subnet: ping works only to one of the VLANs. I run: On sw259: /sbin/ifconfig vlan1 create vlan 1 vla

IP fragmentation

Hi, The IP fragmentation is not like in Linux, and is not clear to me. I'm using 2 FreeBSD-6.3 hosts, connected directly. If I change the MTU of both hosts to 5000, and send "ping" with message size 4972 bytes ( 4972 = 5000 - 8(which is ICMP Header size) - 20 (which is IP Header size) ) from on

RE: It seems that FreeBSD-7.0 does not use the available MTU

This is indeed the problem, thanks. Is this a known issue with FreeBSD-7.0 ? I do not want to hide a potential bug in the NIC driver. Eitan Shefi -Original Message- From: John-Mark Gurney [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 28, 2008 11:02 PM To: Eitan Shefi Cc: freebsd

"ping" with packets larger then 25152 bytes fails.

When I run "ping" between 2 identical FreeBSD hosts, with packets larger then 25152 bytes, "ping" fails. Does someone has an idea what might cause this failure ? Thanks, Eitan ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman
