we are using squid proxy server which runs on redhat 9 version,in my office all pc's internet explorer browser configured for internet with use of proxy server in connection settings.in office we have one database web server which has the link http://192.168.1.249:8500
, i want a iptable rule to ignore the squid proxy server.i don't want to remove internet connection settings from internet explorer for squid proxy server.if i do that they will not access the internet,all time i have to remove and add the internet connection setting for all machines. Requirement of iptables rule is that i don't want to disturb all clients when my proxy server is down.

proxy server: 192.168.1.2
database web server ip: 192.168.1.249
squid proxy port : 3128
