Hi , I have squid with many ips already installed with and configured well with tcp_outgoing directive. The provlem that I face is ; When many pc behind a router with same public ip use the proxy ips. Assume I have 2 pcs Pc1=è Using proxy ip 1.1.1.1 Pc2=èusing proxy 1.1.1.2 Note that 1.1.1.1 & 1.1.1.2 are just for example and we assume those ips are existed on the main server squid. Pc1 & pc2 ips are 192.168.1.100 & 192.168.1.101 and their public ip is 31.220.243.0 I go to pc1 and type “whatismyipaddrss.com “ I see 1.1.1.1 Then I go to pc2 and type “whatismyipaddrss.com “ I see 2.2.2.2 Now lets go back to pc1 and refresh the page whatismyipaddrss.com ===?> then I see 2.2.2.2 not 1.1.1.1 This is my problem. Why sometimes after somefrefresh I get the other ip not ip I put in in browser ?? Could it because same pcs has same public ip ?? I tried to put por for each ip like 1.1.1.1:1333 and 2.2.2.2:1222 …….. but same resukt , the ip keep changes Also I disabled cacing on squid but no luck . Is that a natural thing ? Or squid can be optimized ?
