Ares must be a "leecher" program then. No wonder it's infamous for long queues for downloads.

The idea of forcing people to properly configure their firewalls is so they can share. Since that is what this is all about ... peer to peer. Gnutella is a "file sharing" network. If people weren't sharing then there'd be nothing to download.

If you have a problem with a firewall then it would mean people would mostly fail in their attempts to downld from you.

So why the firewall? Perhaps your router doesn't have good UPnP support & is unreliable in that mode. In which case port forwarding would normally be the best step. Port forwarding instructrions for Marconi can be found here http://www.portforward.com/routers.htm

You posted here, presumably looking for help, but you left very little in the way of details as the forum rules require; details such as these System details - help us to help you (click on link)

I presume you're using Windows XP so did you configure your XP firewall to allow LW full access? (advisable not to have 2 active firewalls b/c they can interfere with each other); Firewall configuration instructions (click on link). You mentioned penicillen, is that only an AV or is it also a firewall?
