You know... I guess that is what i was looking for.  I had a feeling i
was making it much more difficult than it had to be, i just think it
would be that easy.  It only difference is that eth3 is usually up. 
its up with no IP address like i said in the email i posted a minute
ago.  So i would do

ifconfig eth3 down
ifconfig eth3 up 192.168.218.30 netmask 255.255.255.0 gw 192.168.218.2

and you think i should be good like that?  Do you think i will need to
do a service network restart?

and then to set it back up the way i usually have it i could just do:

ifconfig eth3 down
ifconfig eth3 up 0.0.0.0 

and all should be well.   hmmm.  When i get back in my machine finally
i will try all of this.  Thank you for your help.   I still don't
understand why doing it the other way kicks me off and then renders a
completely different interface useless.  Any ideas?
