How do I set up an exception in Avast AVG Business so as to allow an FTP server to connect to a folder on my computer?   I have a Canon WFT wireless transmitter that connects to an FTP server on my computer.   When I disable the AVG protection, the files are transmitted normally, but blocked otherwise.   How do I set up an exception to allow the files to go through.

Normally what I do there is to allow the IP address of the known source (your Canon) . Look in Avast firewall settings for this for an exclusion

I do not know the IP address of the camera.   I think I need to enter the FTP address in the Avast exceptions?   The folder I want the files to get to is on my desktop.   How do I enter the FTP address?

It depends on the firewall settings whether you can enter a name.  You may need an IP Scanner (Famatech) to get the device IP address

Do you need FTP?... FTP does not encrypt passwords etc.
Can't you use SCP (aka SFTP in interactive mode).  (This only requires one port and is easier for NAT if needed etc.).

The FTP server is running on my computer.   Please tell me how to enter the FTP address in the exceptions list.   I assume it is something like FTP:// or something like that.   Thanks.

Safe to assume that was a typo and that you meant "Avast" as opposed to "AVG" because they are both two different products?

The above a given, try the following;

I do not know the IP address of the camera.

On the system that you need to allow, (the computer with the camera attached to it)

Open a command prompt and type ipconfig - that will show you the IP address you need. (The IPv4 address)

Next, obtain the FQDN of the system you need to allow through.

Still in the command prompt, and assuming the IP address is something like (Eg: 192.168.0.2) type;

ipconfig -a 192.168.0.2

That will return the FQDN (Fully Qualified Domain Name) of the system straight after the word "Pinging"

Eg: computername.domain

Now add that "FQDN" name to Avast's firewall as a website exception. (Only enter the name before the full stop as shown above)

That should allow your files through.

Let me know how you go.

Regards, Andrew

It is AVG Business by Avast.   In any case, the camera is not attached to a computer.   It has a Canon WFT transmitter attached to it that uses FTP to transfer the files wirelessly.   When I disable the firewall on my computer the files are transmitted to the shared folder on my computer.   I just need to know how to create an exception in AVG to allow the FTP server to transfer the files.
On a hunch, I just uninstalled then reinstalled AVG.   Now it works perfectly.   Not sure why.

The method of obtaining the IP address and FQDN is identical to what I explained, as is the step of entering the exception into the firewall - whether that be Avast Business or AVG Business, the same process should work.
