Avast firewall blocks local network file sharing

[REDACTED]

I have a local network of 5 computers that are also connected to the Internet. I have Windows XP on them.

The firewall prevents me from sharing files between them. I have to disable the firewall in order to able to transfer files in the local network, but I don't think a deactivated firewall is a good idea when using the Internet.

What do I have to do in order to keep the firewall and be able to share files?

Is the FW set to Private..!?

Tried both settings. No change.

Enable "Internet Connection Sharing Mode" (Firewall -> Settings -> Policies)

My bad. Was given the wrong info.

Turns out the software that is installed on one of the PCs and the other 4 PCs were using through the netowork, was not accessable because of the firewall, so I used the instructions to add an exception.

Sorry. Nevermind.

No problem, thanks for the feedback.

I use AIS and the avast firewall default setting for a new network is 'Public'.  Just so you know.
