RB112 AP, not passing packets

RouterOS General
1

I’ve got an RB112 configured with these interfaces:

ether1: wired to the internet
wlan1: Prism 2511MP, AP mode, no WEP
wlan2: Ubiquity SR2, AP mode, WPA2

wlan2 is routed with public IP space, but wlan1 is behind a NAT rule with private IP space. ether1 is public IP space.

All stations on WLAN2 work perfectly.

All stations on WLAN1 can ping any interface on the RB112, but cannot ping anything past that, i.e. it cannot ping the default gateway past ether1.

Thinking this problem might be the NAT I reconfigured WLAN1 to use public IP space, with the same results.

So - the problem I am trying to resolve, and I am totally and utterly stumped, is why won’t wlan1 communicate?

I’ve configured this before. Dozens of times. It’s set up right, but it just /will not work/… this is so frustrating I’m about to take a hammer to this equipment and call it a day :confused:

At the very most basic level, the router is not routing, and I have NO F*** CLUE why.

Side note, clients on wlan1 can DHCP without a problem, and query the name server on the RB112 without a problem. They cannot, as I said before, communicate with any other IP address, even though those IP addresses can communicate with the RB112.

Sounds like a routing problem or a problem with your nat configuration.. can you post your configs? That way we don’t have to guess.

I reset configuration to default, then reconfigured it exactly the same way, and it works now. Go figure.
