[NoCatNet] Nocat and layer7+ipp2p

[Pulpo]

Hi;

I manage a free-public wireless network, witch Nocat in Openmode, 
transparent proxy and layer7 and ipp2p to control and block (or try at 
least) p2p traffic.

My problem is  that when i run Nocat with the layer7 and ipp2p scripts 
(added at the bottom of initialize.fw file), the network stop working, 
this means there is no captive portal. I attach the scripts i am 
actually using, maybe somebody can helpme or guide me through, to make 
this scripts work with Nocat.

Thanks in advance.

P.S: Please excuse my terrible english :-o
