need a volunteer

[Victor Tsaran]

Hey, FC!
Can you please attach this file with chain rules for me as well?
WOuld be much grateful.

Why did you say to shutdown the 110 and 113 ports. They are used for serving
POP3 client. Don't you need to get your Email once in a while? I would
definitely agree with 23 and 21 to be exchanged for SSH service which also
provides sftp.
