Restrict internet traffic to given ports

sorry if it was already discussed but I didn't find it on the forum, so my apologies.
I'm trying to restrict internet traffic on my LAN, but I have some problems on port 80.
I wrote the following rule in the LAN tab:
TCP "LAN net" * * ALLOWED_TCP_PORTS * none
where "ALLOWED_TCP_PORTS" is an alias for 443,80,2095
Well, the 443 and 2095 works like a charm, but the 80 no!
I can't reach any website on port 80, only 443 (HTTPS).
If I rewrote the rule as:
TCP "LAN net" * * 80 * none
it still not works.
Sniffing the traffic I saw that I correctly resolve the DNS name and then send the SYN packet to the website on port 80…but I never get the website packet back so I cannot connect to.
If need other info please let me know,
