DHCP, BEFW11S4, internal network

Ok.. I've been pulling my hair out trying to get this working (it worked before - why not now!)

Our setup is as follows:

ADSL Modem-----Firewall-----Switch-----BEFW11S4(Ver4)

Our ADSL service goes to a Linux box running Shorewall firewall and contains a public server (web, IMAP, SMTP, VPN etc). We have static IP's from our ADSL provider, but still require DHCP to obtain them. We cannot hard-code them.

Anyway,there is a second ethernet card in the Linux box (192.168.121.x) that is connected to a switch that goes to our internal network. There are other servers and a few local machines conected to the switch. We also have a BEFW11S4 connected to the switch via one of the BEFWssS4's LAN ports.

We previously had the BEFW11S4 setup as a bridge and using WPA-PSK. All of our laptops had static IP's. No problems. We don't want this to be the case anymore as we use our laptops in other locations that use DHCP. We decided to switch the BEFW11S4 to use DHCP for all the wireless clients.

We left the "Internet Connection Type" as "Heart Beat Signal" as we don't have anything connected to the WAN port. This worked for us previously. We have given the router an IP of 192.168.121.30, enabled DHCP, and set the start address to 192.168.121.100 with 5 addresses available for clients. The lease time is set to 0 (max lease time) and the DNS servers are set to our internal nameserver. We have also restricted access to specific MAC addresses as well. Our routing table has one entry: Dest: 192.168.121.0 Subnet: 255.255.255.0 GW: 0.0.0.0 Hops: 1 Inteface: LAN

When a client connects (eg a laptop with an Intel Pro/Wireless

2200BG), it connects to the wireless router (so our WPA-PSK it set up correctly), but it obtains an IP address from our ADSL provider. Even if we disconnect all the cables to the wireless router, it does not give out IP addresses at all.

The laptops work perfectly with other wireless systems obtaining an IP as it should. For some reason, our will not. We have tried rebooting, reset to defaults, updating the firmware, but nothing! I know we have used DHCP on this unit before.

Any ideas?

Thanks for the Help, Mike
