Has anyone successfully built an LRP type DoC image for the WebSurfer? I have a dual ported Intel EEPRO100 compatible NIC that I would like to throw into a poor man's firewall. (Donning the asbestos suit...) I don't recall seeing any threads regarding a successful application of that type yet.
Thanks...

I investigated it, but the main issue is that multiport Ethernet adapters cost a large multiple of the Websurfer unit itself. I have seen a picture of a Zynx 4-port PCI unit that uses the DEC Tulip chip, but it's 10BaseT only. Probably there's a successor that uses the 21143 (10/100) now.
As another side-note, there are NE2000 cards with integrated optical transceivers available for about $50. In principle, it is possible to build long-haul (~50 km) fibre-optic private links with this kind of card.
The reason I mentioned both these cards is that they have Linux drivers.

Don't know if anyone is still interested, but...
I successfully installed the Materhorn release of LRP on the DOC. I upgraded the BIOS to support both card slots at the same time. I removed the RJ45 connector and the LEDS from two network cards, a PCI and an ISA. I placed the LEDs and RJ45s on a piece of PC board and mounted it to the WSP chassis. Using ribbon cable, I wired the RJ45 and LEDs back to the connections on the cards. I had to move a couple diodes and capacitors to the other side of the PCI card. Now both cards fit without any contact or stress. I now have a nice low power and very quiet gateway for my DSL connection. My next project is to set up webserving and FTP service for my lan.

I think it’s worth noting that 2 ethernet cards aren’t necessarily needed for a simple gateway/firewall, especially for the average cable/DSL user who just wants to cheaply split their connection and doesn’t care a whole lot about security. All you need to do to set this up in linux is to enable IP-Aliasing in the kernel, allowing you to assign two ip’s to a single card. Yes, I know this isn't secure or efficient, but it gets the job done a lot easier than resoldering components and a lot less expensive than buying a dual-port card.
