Hi Den!

I don't use DHCP in my network, a little confused how DHCP is involved in this.

My setup is as follows:

Behaves the same on:
Linux vz1 2.6.18-fza-028stab051.1-686 #1 SMP Fri Dec 7 17:44:02 CET 2007 i686 GNU/Linux (P4 netburst)

Linux vz2 2.6.22-ovz005.1 #1 SMP Thu Nov 15 15:35:00 MSK 2007 x86_64 GNU/Linux (Core2 quad)

br0 Link encap:Ethernet HWaddr 00:18:51:52:7C:8C
eth1 Link encap:Ethernet HWaddr 00:50:04:04:0A:D7
veth116.0 Link encap:Ethernet HWaddr 00:18:51:99:F3:C7
veth122.0 Link encap:Ethernet HWaddr 00:18:51:89:DB:CF
veth124.0 Link encap:Ethernet HWaddr 00:18:51:8B:9C:ED
veth126.0 Link encap:Ethernet HWaddr 00:18:51:D0:EB:B7
veth130.0 Link encap:Ethernet HWaddr 00:18:51:A2:C8:5F

Do you think having eth1 HWaddr 00:50:04:04:0A:D7 - might be a problem?
