DMZ Question

Hello,

I have setup a DMZ interface on my Firewall appliance at my job.  When I set my laptop to the static ip address it will get out to the internet and the network connection comes up just fine.

When I connect my Dell Poweredge server to the same network cable with same ip address I get no connectivity.

I have done everything I can think of other than replace a NIC in the server.

I can verify the NIC works correctly on my network internal LAN.  The DMZ will not work with this server and only my laptop.  

Can someone please help me ?

Thank you very much!
