We have set up squid proxy 2.6 on Suse 10.3 with LDAP (Novell eDirectory) with SSO which is working fine. It is like Client ---> Squid ---> UTM (NAT) --> Internet Our UTM (Firewall with Content filter) getting the IP of the Squid only. We want to get the original source (Client) IP at the UTM level. The UTM can not decode the X_Forwarded header of squid. Need suggestion on this. Thankx, Niladri Mukherjee
