TomatoUSB

Hi all! I've googled and searched the forum but haven't managed to find a solution.

I'm quite a noob about Tomato and networking so please be patient with me.
I've managed to upload Shibby's Tomato USB on my ASUS NT-16. And the router connect to the internet through a crappy pppoe modem. On the other side I've a wired and a wireless connection, both working.

Network structure:

[THE INTERNET] <== [CRAPPY MODEM] <== [ASUS ROUTER] <== Wireless client (not captive whitelisted)
[ASUS ROUTER] <== Wired client (captive whitelisted)

Everything seems fine but once I try to enable captive portal I cannot access the internet through the WAN. If I try to access a local address my request is correctly redirected into the splash page but I cannot access anything remotely even if the modem is connected to the internet.
I've whitelisted:
- wired eth
- router eth connected to the wired client
- wired WAN modem eth
- router WAN port mac address

Captive portal is enabled on lan0 that should be comprehensive of any client at the moment, except for the WAN (but I've whitelisted the mac nevertheless because nothing is working).

Once again sorry for my inexperience and awful english.

I've found my error. The WAN was somehow disconnecting starting the nocat and was having hard time connecting due to an ISP issue. Now everything works fine!

So what did you do? :-)

I'm having what sounds like a similar issue on an ASUS rtn66u. Any MAC that I put in the captive portal whitelist simply can't reach the outside world — it's like it's being whitelisted from being redirected to the splash but not from being barred access to the internet.
