The linksys WRT54GS uses a 200MHz Broadcom processor running Linux (2.4.5 kernel, I think) and it has an SPI firewall. If you look at a router's specifications or manual and it shows port forwarding and an ability to block specific ports, protocols, WAN IP addresses, it is probably SPI (statefull packet inspection). I've assumed that the linux-based ones are using IP Masquerading (NAT) and IP Tables firewall, since these are built into the kernel. If you get a linux-based router with open-source firmware/OS, you may be able use 3rd party firmware that gives you more features and options. -- Addicted to Linux since 1998. |
