Hi, I setup linux+bridge+squid+tproxy to see the client IP address on Web server. As the manuals, I configured all the patches and parameters. In squid.conf, I did "linux_tproxy on" but I don't know how to set "tcp_outgoing _address". My squid box is a just bridge not Gateway. Please let me know How to set "tcp_outgoing_address" on bridge mode. Also I put the one IP address, i.e, 10..1.1.100 as tcp_outgoing_address, web server is 10.1.1.120. Then If I browse the URL on Web server, I got the error like followings: ERROR The requested URL could not be retrieved . Socket Failure (99) Cannot assign requested address How can I solve this problem? Also Can I use some gzip compression mode on Squid ? Expecting your kind response.. Eskay Lee
