    Fulvio:

    Only one machine 10.10.10.20 on my LAN is firewalled with the rules below.
    That machine intermittently experienced slow browsing, until last night it simply started timing out all web pages.
    I dropped firewall and browsing was fast again like on all other machines. Rules follow (all of them):

     	1 	* 	* 	DROP udp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 udp dpt:53 	no
    2 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 00:00:00 to 16:30:00 on Mon,Tue,Wed,Thu,Fri tcp dpt:80 no
    3 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 22:00:00 to 00:00:00 tcp dpt:80 no
    4 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 00:00:00 to 09:00:00 on Sat,Sun tcp dpt:80 no
    5 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 00:00:00 to 16:30:00 on Mon,Tue,Wed,Thu,Fri tcp dpt:443 no
    6 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 22:00:00 to 00:00:00 tcp dpt:443 no
    7 * * DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 source IP range 10.10.10.20-10.10.10.29 TIME from 00:00:00 to 09:00:00 on Sat,Sun tcp dpt:443 no

    The router is a P4-2.2 GHz machine with 512 MB RAM booted from a 2.0RC3 CD with profiles saved onto a Kingston 16GB DataTraveler USB key.
    I really need the rules above to work. How can I ensure that both rules are turned on and browsing is OK?
