It's just my humble opinion, but I think using a commercial router to connect your PC, LAN, whatever, to the Internet, is crazy. You just can't trust that shit.

I know I'm about nothing if not repeating myself, but my LAN connects to the Internet through a Linux PC that runs a kernel and an IPTables firewall that I configured myself, here's a fairly simplified version of how I've got it setup:

Code:

Linux computers---
                 |
SGI computers--------Hub---Linux with two NICS firewall---Internet connection
                 |
Sun computer-----

I know that you don't like routers, but I thought that they are designed to do what you do with your NICS firewall and provide wireless access as well. There seem to be solutions for everyone depending on your setup and if you run laptops or other devices that can use wireless access. Those devices that I run on wireless are much more secure than SGI boxes in my opinion. Thanks for sharing your setup.

Have you considered running a VPN router?

Here is a report that studied router security problems: https://www.fkie.fraunhofer.de/content/d...ericht.pdf so you are correct about the vulnerability of routers.
It looks like most routers are running Linux OS with 2 Network interfaces even though you can't call these NICS. You could also run one with a single physical interface with multiple sub-interfaces all using different VLAN IDs connected with a switch with connections to pass traffic according, such as connections to an internal LAN and an uplink to an ISP..

I also do not have a PC with 2 extra slots to add 2 physical NICs at this time.
