I'm having trouble completing a DHCP connection from Tomato to a Mac acting as a WAN router. I'd like to use a Mac running 10.4.10 with an EVDO modem as the WAN connection for my WRT54GL flashed with Tomato v1.09 firmware. I open Systems Preferences:Sharing:Internet -- select the EVDO modem as the device to "Share your connection from" and select "Built-in Ethernet" as an interface to share on. This sets up a DHCP server on the Mac. When I connect the Tomato/WRT54 system with an ethernet cable from it's WAN port to the Mac acting as a router the Tomato firmware will just continually display "renewing ..." and never completes the DHCP request. If I instead connect a second Mac (client mac) to the Mac acting as a router it grabs a DHCP lease and connects through the router Mac fine. In the System profiler on the client mac it lists the following information about it's connection to the Internet: client ip: 192.168.2.2 DHCP Server responses: dns: 192.168.2.1 lease duration (seconds): 0 DHCP message type: 0x05 routers: 192.168.2.1 server identifier: 169.254.61.240 subnet mask: 255.255.255.0 After clicking "release" and then "renew" in the Tomato Overview page I see this in the log: Oct 3 12:30:44 unknown local0.info udhcpc: Entering released state Oct 3 12:31:25 unknown local0.info udhcpc: Performing a DHCP renew Oct 3 12:31:25 unknown local0.debug udhcpc: Sending discover... Oct 3 12:31:28 unknown local0.debug udhcpc: Sending discover... Oct 3 12:31:32 unknown local0.debug udhcpc: Sending discover... Can anyone suggest ways I can troubleshoot this further?
