OT: curious about eth0/eth1

[Tommy McNeely <Tommy.McNeely@xxxxxxx>]

I am curious about why people choose to make a certain interface internal 
or external...

I have always made my "eth0" interface my inside interface.. and once I 
have the box UP and RUNNING (and firewalled), then bring up my outside 
interface "eth1" ... My primary network for smb/nfs/whatever is my inside 
network (thus eth0)... The outside interface is just a "extra interface" 
that I can add on (or move/change/delete) or even make it ppp0 if I happen 
to be changing ISP's :)

I notice several people pick eth0 as their outside interface, and sorta "oh 
yea" the rest of the inside network is on eth1.  I know the linux kernel 
could really care less what they are called, its mostly a "neatness" thing 
I guess... Also it seems like that leaves your box open to attack from the 
time it installs (if you do a NET based install) till the time you get 
around to actually putting a firewall on it.

Again.. I am just curious as to why some do it one way.. and some the 
other... the above is only MY opinion, and could be dreadfully wrong :)
