It sounds like you can connect out just fine, so why bother with configuring a proxy? If you are allowed to send icmp and udp traffic out of the network, a traceroute should show you what hops are on your network. If routing forces all traffic through this proxy, it'll probably be one of these hops. Or, they could be doing policy routing where only tcp port 80/443 traffic goes through the proxy, and all other traffic goes out some other route. In that case, you'll need to use a tcp traceroute program configured to probe on port 80, so it is forced through the proxy. Anyways, it sounds like that company has a few issues with their security policy if it's so easily circumvented. Mike -- gentoo-user@gentoo.org mailing list
