Hi All.
I'm trying to add a vlan tagged interface to a bridge.
I've got an interface called re0 on the server, this is part of bridge0 and bridge0 has an IP address that pings just fine.
I now create a vlan tagged interface thus:
ifconfig re0.33 create vlan 33 vlandev re0 up
If I put an IP address on that, it pings just fine.
OK, without that IP address, I now create bridge1:
If I now put an IP on that bridge instead of re0.33, it does not ping.
If I do a broadcast ping from another host on that network thus (Solaris system issuing the ping):
ping -sn 192.168.33.255
I can see packets arriving if I
However, on neither interface do I see any pings coming in when I ping it's own address (in this case 192.168.33.20).
The Solaris system issuing the pings has learned the arp address of the bridge though:
If I
So as you can see, the FreeBSD system does get ARP requests and does respond to them, but the pings never get there....
And here's the ifconfig output on the FreeBSD system being pinged:
There are no firewalls involved at all here.
Any pointers greatly appreciated.
Thanks.

I can see packets arriving if I
tcpdump -i re0.33
and if I tcpdump -i bridge1
However, on neither interface do I see any pings coming in when I ping it's own address (in this case 192.168.33.20).
The Solaris system issuing the pings has learned the arp address of the bridge though:
Code:
root@gaspra # arp -an | grep 192.168.33.20
net1 192.168.33.20 255.255.255.255 02:a7:91:b6:3a:01
tcpdump -i bridge1
, I do get some packets, but not any echo requests:
Code:
root@bianca # tcpdump -i bridge1
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
