Last week a router was connected to our LAN. The router belongs to a 'mobile' class solution.
This router has DHCP server configured at its local side and dhcp client toward its LAN side.
The next day we were in big trouble. Not one client on the LAN could connect.
Shortly afterwards it was discovered that the default gateway in all the scopes configured on a MS DHCP server.
The strange thing, to me, was that I got several dhcp-snooping messages (SNMP) from a switch
on which I had configured with dhcp-snooping. Unauthorized server !!
I was surprised because was the message contaned the ip-address from the router but later on the
message contained zero's.
Furthermore strange because the router only has dhcp server configured for its inside.
Has anyone the same problem or is known with this issue.
How can I resolve it if it is a Cisco related problem?
