netstat -r

You can only change it with the route command, a routing protocol 
daemon, or processes such as pppd which know how to talk to the 
routing table

what is your current routing table?
does your proxy server forward traffic?  or is it a squid/socks kind 
of proxy server?

I assume they are like Cisco routers and use whatever protocol they 
are configured to use.  You can run something like etherape or tcpdump 
to watch the raw packets and the routing protocol will make itself 
apparent.
