I've posted before that this router confuzes the hell out of me but regardless I need to get it working. I've been using it as a wireless switch by setting up a bridge between ethernet1 and wan1 using Winbox. Then letting windows internet sharing act as the DHCP server. I would love to have the routerboard 500 act as a DHCP server but I cannot figure out how to do that. I created an IP pool and setup the WAN1 as a dhcp server and it sends out IPs but I cannot get it to pass internet through it which is coming in from the ethernet1 port.

What am I missing?

Draw/attach a simple diagram of your setup , include all the ips of dsl router etc , makes it easier to help you.

incoming internet goes into lan 1. Its setup for DHCP there with a public IP address. Lan 2 connects directly to a wireless router. I am using windows xp and internet sharing is enabled so Lan 2 has the IP of 192.168.0.1. The wireless router (routerboard 500) is setup to receive a DHCP IP address from Lan 2. So it gets an address of 192.168.0.100, generally.

From there I want the routerboard 500 to assign IPs to any wireless clients. Currently the routerboard is setup like a switch so wireless customers are getting IPs from the windows internet sharing which is working, but Id rather have the routerboard handle all the DHCP.

So basically, I want the ethernet1 port to obtain an IP via DHCP, then I want the wan1 port to act as a dhcp server to any wireless clients. Like any storebought router would do.

Hi, its more simpler if you build one bridge interface and put ether1 and wireless (AP mode) on bridge. If you want to make the routerboard as DHCP-relay you can use DHCP-relay feature.
I just wondering if you already have routerboard as router why you still use windows

Sorry for my bad english.

Because I haven't gotten it to work as a router. I am missing a step. If I setup the router as a dhcp server on WAN1 and setup ethernet1 to obtain via DHCP it doesnt work. The wireless computers do get an IP from the routerboard, but internet is not available so I think im missing a step somewhere to pass internet through ethernet1 to wan1.

You need either a source-nat or masquerade firewall rule to do what you are trying to do - the internal address needs to nat/masq to an external address. Since you are using dhcp-client, you'd be best off using a masquerade rule with the source address as your internal IP subnet.
