12.6 FTP Policy
To define rules for access to FTP servers go to Configuration → Content Filtering → FTP Rules.
Figure 12.14 FTP Rules
Rules in this section are tested from the top of the list downwards (you can order the list
entries using the arrow buttons at the right side of the dialog window). Testing is stopped
when the first convenient rule is met. If the query does not match any rule, access to the FTP
server is implicitly allowed.
Note:
1. The default WinRoute configuration includes a set of predefined rules for FTP traffic. These
rules are disabled by default. These rules are available to the WinRoute administrators.
2. A rule which blocks completion of interrupted download processes (so called resume func-
tion executed by the REST FTP command). This function is essential for proper function-
ality of the antivirus control: for reliable scanning, entire files must be scanned.
If undesirable, this rule can be disabled. This is not recommended as it might jeopardize
scanning reliability. However, there is a more secure way to limit this behavior: create
a rule which will allow unlimited connections to a particular FTP server. The rule will take
effect only if it is placed before the Resume rule.
For details on antivirus scan of FTP protocol, refer to chapter 13.3 .
