I added the additional udp info to my Squid configuration and restarted both Squid and LVS and LVS still sees the connection to the VIP as an inactive connection. Anything else I could provide or any other suggestions? -----Original Message----- From: Ding Deng [mailto:ding.deng@xxxxxxxxx] Sent: Wednesday, September 19, 2007 12:00 AM To: Brad Taylor Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: LVS & Reverse Proxy Squid "Brad Taylor" <btaylor@xxxxxxxxxxxx> writes: > We use LVS (load balancer) to send traffic to multiple Squid 2.5 > servers in reverse proxy mode.

You need as many public addresses as number of Squid instances you'd like to run in a single box, and configure each instance to listen on a different public address, e.g.: Instance 1: http_port 192.168.60.7:80 http_port 168.215.102.126:80 udp_incoming_address 192.168.60.7 udp_outgoing_address 255.255.255.255 Instance 2: http_port 192.168.60.8:80 http_port 168.215.102.127:80 udp_incoming_address 192.168.60.8 udp_outgoing_address 255.255.255.255 Hope that helps.
