Privet :-)
In case, you can ping/connect from the router itself, I would guess, the missing MASQUERADE in the firewall is the issue.
BTW: As I have a similar system up and running, depending upon your requirements, coova-chilli is a much more powerful captive portal. Which modem do you use ?

Privet!)
I use tp-link mr-3020 with Alcatel x230s 3g modem. Modem has sd-card, which i use for extroot.

The discussion might have continued from here.
