Hi, You will want to make sure that you have this rule before the divert rule allow tcp from (live ip address) to any otherwise squid will go into a forwarding loop. You do not need ip-transparent if you are using IPFW to do the divert. Oh yes the headers are from the live ip of the squid box. I know there is a way to pass the clients ip to the remote site. Check on the squid web page regarding that.
