Hi:
I'm beginning to learn something about the iptables to develop a simple parental control. Experimenting, I've found the following for me unexplainable behaviour:
From my Android mobile in the wireless WIFI LAN at 192.168.1.9, with Dolphin Browser, I try to visit a web page (for instance, www.google.es). If I leave the iptables alone (as originally created by the FW), the page loads correctly and completely. However, if I instert a rule with the command "iptables -I FORWARD -s 192.168.1.9 -j ACCEPT", Dolphin begins loading the page, but it doesn't complete (it happens also with many other web pages, but not with some others) . With the same resulting table, from my mobile, ping command works OK and the same page is completely loaded with the android chrome browser.
I suppose it will be due to some operation done with the connection some lines below in the FORWARD table that gets not done when the ACCEPT aborts further flow, but, could anybody with more knowledge about iptables explain it, please?
Thanks,
Juglar
