If so you can port-forward to reach it like: In one terminal window: ssh -L3128:squid_host:3128 relay_host (perhaps the same host running squid...) and in another: http_proxy=http://localhost:3128 ftp_proxy=http://localhost:3128 yum update If you are really desperate, you might try installing VMware Player on windows configured for NAT networking with a Centos guest. I believe that will piggyback your outbound connections through your windows host and its isa firewall client. -- Les Mikesell lesmikesell at gmail.com
