Unable to get DHCP lease
Posted on 2010-08-23
We are having an issue with DHCP leases on our network. Up until this point we only used static addressing. At this time we need to be able to pull dynamic lease from one of our DCs. In this instance our LAN_Client and LAN_DC just are not playing nice. If you static the client devices IP they are able to communication with everything on the network.
How things move: Client>DHCP Request>Switch>Firewall>Switch>Server
Our firewall policy is wide open at this time for traffic between the two VLANs. The switch that is passing data is a PowerConnect 5424.
Detailed movement: Client>DHCP Request>Switch>VLAN 15>Firewall>VLAN 10>Switch>DHCP response>Client
If we take a client device and connect it directly to VLAN 10 it is able to pull a dynamic address.
Any thoughts as to what would be causing this?
