Dear friends, After reading mailing lists & Web & FAQ I couldn't find answers to these: stunnel.conf as follows: debug=7 client = yes [proxy] accept=1111 connect=62.215.5.69:8080 (Public SSL Proxy) protocol=connect protocolHost=stunnel.mirt.net:443 CLIENT(Browser+Special software)<->firewall<->(Internet)<->Public SSL Proxy<->WEB SERVER Public SSL Proxy as follows: http://tools.rosinstrument.com/raw_free_db.htm?t=2 Only the CLIENT side have stunnel. After running stunnel 4.34 (Windows binaries). Then. Browser http://localhost:1111/ But Sniffer can monitor the command-(CONNECT stunnel.mirt.net:443). The problem as follows: Only the CLIENT side can install special software. Special software including but not limited to stunnel. If the firewall can block many websites depend on Web IP & URL. How to pass through the firewall base on Public SSL Proxy? How to encrypt the URL-(stunnel.mirt.net:443)? What is the special software? If stunnel can solve this issue. How to configure? Best regards, cpu
