IPNetRouter is the simple, low-cost way to share your cable modem, xDSL, or dial-up internet connection with your entire LAN. With IPNetRouter, you can use multiple IP interfaces at the same time (such as Ethernet and OT/PPP for example), and specify additional routes for communicating with more than one IP gateway.

IPNetRouter is a complete IP router and firewall solution including a built-in DHCP Server, NAT with inbound port mapping, and IP filtering to setup your own firewall. Other features include support for PPPoE and Quicktime streaming. IPNetRouter's OT native design offers superior performance easily outperforming other low-cost hardware and software solutions.

IPNetRouter also directly functions as a DynDNS client. This means that you can run a Web/FTP/Video server and have remote users easily find your dynamically assigned IP address (no need for a more expensive static IP address). You just need to sign up for an account with DynDNS.org. The cost savings from this feature alone easily can pay for IPNetRouter in a couple of months!
