Well, it seems and the Linux kernel can’t bridge dissimilar network types, which means I can’t bridge Ethernet and Firewire (workaround until I replace my NIC in my desktop because it fried, having my laptop route for my desktop).<\/p>\n

My laptop’s IP is 192.168.2.4
\nMy desktop’s IP is 192.168.2.2
\nMy router’s IP is 192.168.2.1<\/p>\n

So, the work around seems to be this…<\/p>\n

On the laptop, with eth0 already up:
\nifconfig firewire0 up 192.168.2.4
\nroute del -net 192.168.2.0 netmask 255.255.255.0 dev firewire0
\nroute add -host 192.168.2.2 dev firewire0
\niptables -F
\niptables -P FORWARD ACCEPT
\necho 1 > \/proc\/sys\/net\/ipv4\/conf\/all\/forwarding
\n<\/code><\/p>\n

On the desktop:
\nifconfig firewire0 up 192.168.2.2
\nroute add default gw 192.168.2.1<\/code><\/p>\n

To make this permanent, you would edit \/etc\/networking\/interfaces<\/code> like this…<\/p>\n

On the laptop:
\nauto eth0
\niface eth0 inet static
\naddress 192.168.2.4
\nnetmask 255.255.255.0
\nbroadcast 192.168.2.255
\ngateway 192.168.2.1
\npost-up ifconfig firewire0 down
\npost-up ifconfig firewire0 up 192.168.2.4
\npost-up route del -net 192.168.2.0 netmask 255.255.255.0 dev firewire0
\npost-up route add -host 192.168.2.2 dev firewire0
\npost-up iptables -F
\npost-up iptables -P FORWARD ACCEPT
\npost-up echo 1 > \/proc\/sys\/net\/ipv4\/conf\/all\/forwarding<\/code><\/p>\n

On the desktop:
\nauto eth0
\niface firewire0 inet static
\naddress 192.168.2.2
\nnetmask 255.255.255.0
\nbroadcast 192.168.2.255
\ngateway 192.168.2.1
