avast! ports

I would like to know which ports does avast! use

Thanks!

Which version of avast do you mean, exactly?
Also, do you mean which ports does avast open (listen on) or which ports it uses to communicate (outbound) etc?

Thanks

avast! 4 Server Edition
Both cases, if possible :slight_smile:

By the way, you have a great product!

Well, it doesn’t really listen on any ports for non-localhost traffic.

The Internet Mail provider listens on 12025/tcp, 12110/tcp and 12143/tcp on which it routes regular port 25 (SMTP), 110 (POP3) and 143 (IMAP) traffic. But the ports are only open for localhost access.

The WebShield provider does the same for 12080/tcp (routing port 80, i.e. HTTP) traffic.

The updates are fetched using regular HTTP protocol (port 80 - unless instructed to use a proxy server on a specific port).

That’s pretty much it. The situation is very different with ADNM (the network management suite) which uses several tcp and udp ports to implement the communication between the management server and the agents.

Thanks
