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
