Re: [Xen-users] 8th DomU can ping bridge but not internet

["Peter Braun" <xenware@xxxxxxxxx>]

SOLVED! :)

The problem was caused by ISP/colohouse.

Server is connected via single ethernet port and there was MAC filter
to 8 MACs per port.

Now they removed MAC filter on ethernet port and new domUs without problem.

I would like to thank people here on mailing-ling, hundred_  and
FuzzyB on ##xen on irrc.freenode.net and grifferz of bitfolk.com for
asistence.
