6224 DHCP Relay and VLANs
Hi,
I'm trying to configure a PowerConnect 6224 for a new building on our site and am having some difficulty getting DHCP to work.
The aim is to connect the 6224 to our existing network, which is the 192.168.234.0/24 subnet and for clients on this switch to be on the 192.168.236.0/26 subnet. I have created VLAN 2 for 192.168.234.0/24 and VLAN 4 for 192.168.236.0/26 and assigned 192.168.234.241 and 192.168.236.1 as the interface IP addresses respectively.
I have enabled the DHCP relay and configured it to contact our main DHCP server, which the switch can ping, but when I connect a workstation to port 1 it fails to receive a DHCP address. I have configured a scope for 192.168.236.0/26 on the DHCP server (Win 2k3) and if I configure an IP address manually the workstation can ping through to the 192.168.234.0 subnet.
Any ideas on what I am doing wrong here?
Thanks,

As a further test I'm going to set up the second 6224 which I have and then check the stats for the DHCP relay to make sure it is actually receiving the DHCP discovers. I've had a look at the other thread, but haven't come across anything there which works for me.
Thanks,
