Is it possible for specific workstations to be configured to download the database updates from Avasts servers direct, instead of our own main server. This would be massively useful for remote workers with limited VPN bandwidth.
What ports does Avast communicate on so that I can allow them in the firewall for cross-network traffic.
In the SBC console you can set group settings, somewhere in there is the option to have the client look for internet updates when it cant find the SBC server in the network.
There is MirrorURL property in Expert Settings of a Group. If connection to this URL fails then client will try to connect avast servers directly (of course, if you check the update from internet if mirror fails.
