Slashdot has a current discussion about which domestic router is best for Quality of Service (QOS) provision for Voice over IP.

The original question posed is by someone using a Linksys WRT54G wireless broadband router with Bittorrent and other high-bandwidth applications to consider. Unfortunately, the WRT54G isn’t quite cutting it when used alongside Vonage.

Inevitably for Slashdot, there is some gravitation toward open-source products. Open firmware for the WRT54G is suggested by some while another comment mentions that m0n0wall, an open-source firewall VPN distribution, can be deployed on relatively low-end commodity hardware and provides the type of QoS required.
