Re: Proxy Server Setup Problems



Dear Nilesh, 
	Thanks you very much for your information.  
	Now I removed  
		NAT chains entries 
		IP Masquerades  
		IP_forward 
	But I am missing the following options 
		tcp_outgoing_address 
	Now I add "tcp_outgoing_address" and now OK. Here is what I did 
 
		acl net1 src 192.168.1.x/24 
		acl net2 src 192.168.2.x/24 
		tcp_outgoing_address 10.x.x.x net1 #real IP 
		tcp_outgoing_address 10.x.x.x net2 #real IP 
 
	But proxy access is too slow. So, I am finding now to speed up Proxy 
access Speed
