Okay, I'll be syncing m0n0wall 1.21 capitve portal in a bit.

Thanks for the info.

Is your Wireless bridged to another interface?
Is it working with same configuration if you disable the captive portal?
Also please consider upgrading to 0.95 (newest version while typing this).

@sniffer:

I know, im not the first to ask this question.

Did you think, it will be in the future a cool option to integrate Captive Portal on multiple interface ?

Thanks for your support!

Not planning on doing so.  However someone else can do the grunt work and submit patches.
