No new boxes. Not possible for any other box to be assigned the same ip internally via dhcp and definitely not the same Internet ip.
Exactly. DHCP server would check for a conflict before assigning an address and is definitely not the source of the problem.
Perhaps you care to explain why BOTH vlan interfaces stopped working? The odd chance that two other boxes each took one of the other ip address?
Did not know that both had stopped. Conflicting IP addresses was just a suggestion. May not be the problem at all. With bonding, breaking one might break both down at the MAC level ...
Hmmm ... which bond mode are you using?
The box with the problem just so happens to be the only box using bonding, 802.1q and a four port Qlogic Netxen NIC. I think the chances of there being a problem between these three more likely than some 'ghost' boxes getting assigned the same ip addresses when I am the only admin around.
If you are the only admin, then its not that likely. Then again, I once had a power spike reset a wireless router on my network without me knowing. Default settings were close by not quite right, and it took me a couple of days to track down the problem :-(
If it was working, then suddenly stops, then something must have changed. I gather you have some configuration and change management system in place? Backups of conf files?
