The 6248 has no default gateway. It will not let me put 192.168.1.1 because it does not reside in the same subnet as the 6248 (192.168.99.1) The 2708 has 192.168.1.1 listed as its default gateway. At this point, the network has too many complexities for me to untangle. I'm very glad that at the least I have DHCP resolved for when we finally migrate our server to the new location. Once the server is in place, and the gateway/firewall are plugged directly into the 6248; I will revisit the proper configuration of this network. Some tips to anyone who might have a similar issue: Check your management VLAN. It cannot be the same as VLAN 1 if you expect routing to work from VLAN 1 to anywhere else because the management VLAN cannot be routed. Also check static routing from your gateway, make sure the gateway has a return to the ips of your VLANS ie: 192.168.2.0 255.255.255.0 gateway_ip Thats all for now. Thank you everyone who has contributed
I have created two new DHCP scopes in my windows server 2003:192.168.2.0 - Public, and 192.168.3.0 - VOIP. This DHCP server is connected to a Dell powerconnect 2708, which is connected to our new powerconnect 6248P via fiber point to point. In the new network computers on the default VLAN 1 are correctly being assigned IPs as they connect. I have issued the following commands to the 6248's CLI: enableconfigurevlan databasevlan 20vlan 30exit configureinterface range ethernet 1/g1-1/g2switchport mode generalswitchport general allowed vlan add 20switchport general pvid 20dhcp l2relayexitconfigureinterface range ethernet 1/g3-1/g6switchport mode generalswitchport general allowed vlan add 30switchport general pvid 30dhcp l2relayexitinterface ethernet 1/g11switchport mode generalswitchport general allowed vlan add 20switchport general allowed vlan add 30dhcp l2relayexit configureinterface vlan 20name "PUBLIC"routingip address 192.168.2.1 255.255.255.0ip helper-address 192.168.1.150exitconfigureinterface vlan 30name "VOIP"routingip address 192.168.3.1 255.255.255ip helper-address 192.168.1.150exit ip routing I have also tagged all traffic on VLAN 20 and VLAN 30 on ports 1/g11 (6248) and port 2 (2708). VLAN 1 access has been removed from ports 1/g1 - 1/g6 (6248) Everything appears to have been set correctly, but I am unable to get any answer from the DHCP server on any ports attached to VLAN 20. Is the powerconnect 2708 unable to pass the relay to the server? Is it possible something is getting dropped in the point to point? I'd greatly appreciate any comments or suggestions, thanks!
