proxy and block issues

[topcj]

When I use a proxy and block a certain program, that program can access the Internet.

1. Let's assume that you use local proxy, so its address is 127.0.0.1 and e.g. port 3128
2. When a certain program connects to Internet via proxy, then it connects to 127.0.0.1:3128
3. If you want to filter the 127.0.0.1 address, then:

• remove (or comment) the 127.0.0.1 from the Options: IP Addresses: Internet Addresses: Exclude (so this address will be not auto-allowed):
  
• turn on the "Filter local addresses" flag in the Options (so the 127.0.0.1 and 255.255.255.255 addresses will be not auto-allowed):
  

BUT you must be careful with filtering the 127.0.0.1 (loopback) address, because some programs use it for inter-process communication (IPC)!

Thank you very much it worked for me
