udp_incoming_address is correct, I don't know why its breaking. Can you send us a config file ? You could of course just deny access to the port on the other cards for an easy fix... Through some other mechanism. -----Original Message----- From: Vadim Pushkin [mailto:wiskbroom@xxxxxxxxxxx] Sent: 11 November 2005 11:10 PM To: squid-users@xxxxxxxxxxxxxxx Subject: Need To Bind ICP To Specific Interface hello again; I have built three squid proxy servers, 2-5.STABLE11, on Solaris. I have all three machines with two network interfaces (Gbit) each. The first interface is used for connections to/from my clients, as well as to the Internet (allowed by a firewall rule). The second interface, I am trying to use to establish an ICP LAN. So far I have been able to get all three machines talking to each other via this interface, but I have not been able to lock down the interface at which ICP listens on to just one interface, i.e.: # netstat -a -f inet | grep 3130 *.3130 Idle If I tweak my squid.conf to use the second ports IP address under udp_incoming_address, then I am able to see that it is listening on this port, but then all requests to the proxy fail, ICP or not. I have already created an acl for this interface as well. Could someone please help? Thank you, .vp
