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):

Code:
    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?
