DragonFly bugs List (threaded) for 2005-02
ARP and bridged interfaces.
My DragonFly box is configured with the vr0 and vr1 interfaces bridged.
vr1 is assigned an IP address of 192.168.20.4 and vr0 has no IP address
assigned. This is resulting in unexpected behavior.
The bridge operates as expected, PCs (A) and (C) can communicate as
normal. The problem I'm experiencing is with ARP requests for
192.168.20.4 and machines connected to the vr0 interface.
PC (A) can NOT see 192.168.20.4 and the DFly box can not see PC (A).
Adding static ARP entries on PC (A) and the DFly box solves the problem.
(PC (A) can use the MAC address of vr0 or vr1 for 192.168.20.4)
The "who has 192.168.20.4" ARP requests issued by PC (A) go unanswered.
The "who has 192.168.20.50" ARP requests issued by DFly get a valid
response but are ignored. (ARP table is not updated.)
DFly and PC (C) communicate normally.
[ PC (A) ]-----[ DFLY BOX (B) ]-----[ PC (C) ]
[ DHCP CLIENT ] [ VR0 VR1 ] [ DHCP SRV ]
192.168.20.50 .20.4 .20.1
This is not the behavior under FreeBSD 4 or previously under DragonFly.
I'm running Stable from yesterday.
Any help would be appreciated. (2nd problem to hit this machine in as
many days! :) I tried to SSH in from PC (A) to get at some core dumps!)
