I don't have a computer on that lan, nor do I want to put one there. I've temorarily abandoned my original idea of having the router providing dhcp on the secondary lan while passing the dhcp options to the clients on the secondary network and went back to basics. Setup dhcp relay on the router and I get a bit further, I see the router (and the dhcp server) passing the dhcpdiscover and dhcpoffier messages back and forth, but the client never does a dhcpack. Further testing this morning seems to implicate the wireless bridge as part of the problem. I took it out of the equation, hooked the mvp direct to the dmz port on the router, setup a logical lan for the dmz side and setup dhcp relay between the dmz and internal lans and lo and behold it works..... whoops not quite, I see the mvp get an address and see loading application on the screen, then it goes back to trying to contact the dhcp server The dhcp relay logs on the router show this # (xid:2f8ed8b5) L2 socket: received request message from 0.0.0.0:68 to 255.255.255.255 at dmz (xid:2f8ed8b5) got a DHCPDISCOVER (xid:2f8ed8b5) Warning! can't get server id from client message (xid:2f8ed8b5) forwarding dhcp request from 10.88.65.254:67 to 10.11.12.10:67 (xid:2f8ed8b5) sent a dhcp packet of 251 bytes to server 10.11.12.10 (xid:2f8ed8b5) got a DHCPOFFER (Not an error): dhcp packet xid mismatch(2f8ed8b5). try next server (xid:2f8ed8b5) got a DHCPOFFER (Not an error): dhcp packet xid mismatch(2f8ed8b5). try next server (xid:2f8ed8b5) got a DHCPOFFER (xid:2f8ed8b5) from server 10.11.12.10 (xid:2f8ed8b5) Send unicast to client, devidx 5 ip 10.88.65.145 mac 0:d:fe:0:92:a8 (xid:2f8ed8b5) sending dhcp reply from 10.88.65.254:67 to 10.88.65.145:68 (xid:2f8ed8b5) Delete the arp entry used by unicast On the dhcp server itself I see Nov 10 10:12:33 sinclaire dhcpd: DHCPDISCOVER from 00:0d:fe:00:92:a8 via 10.88.65.254 Nov 10 10:12:33 sinclaire dhcpd: DHCPOFFER on 10.88.65.145 to 00:0d:fe:00:92:a8 via 10.88.65.254 Nov 10 10:14:37 sinclaire dhcpd: DHCPDISCOVER from 00:0d:fe:00:92:a8 via 10.88.65.254 Nov 10 10:14:37 sinclaire dhcpd: DHCPOFFER on 10.88.65.145 to 00:0d:fe:00:92:a8 via 10.88.65.254 Oddly, I see nothing whatsoever in the tftp server logs (I have logging turned up so I do see log entries for mvp's on the same lan) At this point the mvp starts cycling through contacting mvp bootserver and contacting dhcp server over and over and I see no further dhcp traffic on the router, dhcpserver or the tftp server. -- Harondel J.
