Setting Proxy server in Ubuntu

[rasheedahme27]

Hi Fiends,

please help me to set up proxy server on my ubuntu desktop..

i need to forward my all Pc's traffic through this desktop (all these PC's in same network)

my TL said to do this concept using iptables. on Ubuntu desktop.

sorry for my bad english..

Thanks

1. Open squid configuration file.
2. create an ACL for your network
3. Allow that ACL to access internet.
4. Restart squid services.
4. Setup net forwarding in /etc/sysctl.conf
5. Configure IPTables to forward rest of the traffic to internet
       # iptables -t nat -I POSTROUTING -o <external interface> -j MASQUERADE
