Sharing Internet for multiple clients

1.1.2.16 whateveryoucallit. Can it serve multiple local clients sharing the 3G/4G connection?
At the moment, I have 2 notebooks (over WLAN) and/or the on-board browser (mostly Firefox for Android) trying to work together. Only one of the three does work normally at a time, that is, can use HTTP. Tcpdump-ing at the other notebook shows that HTTP packets are sent yet never answered. Once the "working" client remains inactive for about a couple of minutes, one of the others gets a chance.
My first idea was a broken NAT stream detection mechanism, as the symptoms and timeouts are typical for such bugs. Yet other protocols, including ICMP (ping), UDP (DNS, NTP), and even TCP on the other ports (IMAP/POP3/SMTP secure or unsecure, and even HTTPS) do work normally at that time!
Is there a built-in "transparent" proxy specifically for HTTP traffic? If so, then 1) what is it needed for? 2)it is buggy.
