The problems just started today. This machine runs "fine" since a few month. 
But after a reboot this morning the troubles begun...

To be more clear:
I can't reach the guests neither from the network nor from the dom0 itself - 
but I can reach then dom0 from the network. This make me think that there must 
be something wrong with the internas of xen or the virtual networking stack.

I'm using the bridging mode by the way.
