Now that I've got my hierarchy stuff figured out I've stumbled across my next problem... How can I bind a particular squid instance to a particular address on the UDP side? It's easy with tcp - hostname:port but if I do this for udp_port it doesn't work, Squid always listens on all addresses for a particular UDP port. I need to either bind the UDP traffic to a particular address or figure out a way to re-route the outbound UDP traffic to a different gateway than it would otherwise. Bryn
