Hi all, I have been pounding through documents and forums for the last few days trying to get my setup going (might not be optimal, suggestions welcome). I almost have it but I seem to have a routing issue. Here is the setup
I’m trying to connect three remote sites to a main site that has Internet access.
I have One AP (Groove) with three Stations (SXT). I want each site to be on a different subnet so I have setup three virtual APs with their own subnet.
My laptop can connect via wireless to the AP and can access the Internet fine. My stations are also connecting to the AP just fine and can also ping out to the Internet. But if I connect my laptop to the station via ethernet I can’t ping the AP or get to the Internet. I can ping the station but that’s it. The laptop gets its ip from the station. I have tried assigning it a gateway of both the AP (10.1.101.1) and the station (10.1.101.2) with the same results.
The station setup is very basic two interfaces (ether1 and wlan1) bridged with a single ip (10.1.101.2) for the bridge. The ip for the virtual AP I’m connecting to is 10.1.101.1. There are two routes on the station
10.1.101.0/24 - bridge1
0.0.0.0/0 - 10.1.101.1
On the AP there is also the same route different gateway
10.1.101.0/24 - wlan1
0.0.0.0/0 xx.xx.xx.xx - (my public address)
It’s probably something basic that I’m missing. I really appreciate the help, thanks.
Each interface on a routerboard is generally going to be a separate routed interface. This means you will either need to put a subnet on the Ethernet interface and set up routes so traffic can get out, or bridge the Ethernet interface with the wireless so it acts as a layer2 device.
Thanks for helping me. Here is the provided for both AP and one station. xx.xx.xx.xx is the private ip.

Good call guys. The “station” was in station mode and after doing some reading that mode does not do bridging, even though it lets you configure it that way. Since the docs do not recommend station-bridge mode, I’ll be looking into doing wds-station or wds slave. suggestions on what would be best to use?
I’m not worried about bandwidth right now, I’m limiting each station to 3Mb.
So I’m thinking I’ll leave the wlan and ether interfaces on the AP unbridged since the ether port will have the public ip and then I’ll nat out from the wlan. Then on the stations I’ll bridge the wlan and ether interfaces. Does this sound right?
I did some more reading and I decided to go with the station bridge mode. Everything is up and running on all three stations and everything looks good. Thanks for all the help and suggestions.
