The NXC is not applying my application patrol bandwidth management settings.
Bandwidth management in policy routes has priority over application patrol
bandwidth management.
The NXC's performance slowed down after I configured many new application
patrol entries.
The NXC checks the ports and conditions configured in application patrol entries in
the order they appear in the list. While this sequence does not affect the
functionality, you might improve the performance of the NXC by putting more
commonly used ports at the top of the list.
The NXC's anti-virus scanner cleaned an infected file but now I cannot use the
file.
The scanning engine checks the contents of the packets for virus. If a virus
pattern is matched, the NXC removes the infected portion of the file along with the
rest of the file. The un-infected portion of the file before a virus pattern was
matched still goes through. Since the NXC erases the infected portion of the file
before sending it, you may not be able to open the file.
The NXC is not scanning some zipped files.
The NXC cannot unzip password protected ZIP files or a ZIP file within another ZIP
file. There are also limits to the number of ZIP files that the NXC can concurrently
unzip.
The NXC is deleting some zipped files.
The anti-virus policy may be set to delete zipped files that the NXC cannot unzp.
The NXC cannot unzip password protected ZIP files or a ZIP file within another ZIP
file. There are also limits to the number of ZIP files that the NXC can concurrently
unzip.
