[SLUG] SQUID BEHIND A FIREWALL

[jware]

I am installing Squid, a proxy server, behind a firewall. Squid server ip is 192.168.1.200, the firewall ip is 192.168.1.1   The proxy is parent with Telstra proxy.cache.telstra.net. The port for http/ftp is 3128 icp is 3130. My Squid.conf file is:   cache_peer proxy.cache.telstra.net parent 3128 0 no-query default acl all src 0.0.0.0/0.0.0.0 never_direct allow all   I 've got tcp_denied message in the cache.log file.   I believe it is to do with the firewall.   My firewall setup is   INput ipchains input -A -j ACCEPT tcp -s proxy.cache.telstra.net -d 192.168.1.200 OUTput ipchains output -A -j ACCEPT tcp -s 192.168.1.200 -d proxy.cache.telstra.net 3128   What are the ports used when the cache server communicate? Is my firewall script adequate to deal with the traffice between the 2 proxy server?   Regards David Kwok
