Re: squid+p2p+donload limit

Hi Asish,

Answer 1 : configure IPTABLES(firewall)in Linux Squid to prevent users accessing HTTP

Answer 2: YES u can block using Access-list

Answer 3: using QoS YES u can restrict the bandwidth, also using delay pools in Squid based on the IP address or subnet you can restrict the Speed of the internet.

hope this helps.

Re: squid+p2p+donload limit

thanks 4 reply,

regarding 1 ans: my squid working on port 8080 can i block rest of the port in ip table.

regarding 2 ans: i did the same ,i blocked p2p but i think its not sufficent to block p2p site and p2p port coz its using random port. As all p2p having well define port but after blocking well define port its start communicate on some other free port.

regarding 3 ans:can u provide me any documnet. basically i want to reserve 50% of 2 mbps link for http /https and rest for other protocol. I also want to limit downloading speed also at router end.

As u mentioned earlier "using delay pools in Squid based on the IP address"....can u plz explain in datails.

Thanks alot
