Interface missing in Pool:Edit

[Arrested]

Hi.

I have a problem trying to setup outgoing Load Balancer (on 1.2.3-RELEASE version). For some reasons, not all my WAN interfaces appears in drop down list in Interface Name section:

I have 2 WAN interfaces (em0 and em1), and 1 LAN interface (bge0). They all are correctly configured, but it seems like i'm missing something somewhere. Switching interface assignments didn't bring any luck.

Any advice would be very appreciated.

Thanks.

Did you make sure the OPT is acutally enabled?
Did you configure a gateway on the OPT?

Sure, opt1 in correctly configured and reachable from other networks.

If it's not showing up there it doesn't have a gateway (and hence isn't a WAN).
