[Samba] samba and server availability

[Blake Patton]

Greetings, I have a samba server working fine, it is on a stock debian 
box, with 2 nics, one inside and one outside. The problem I have is that 
when the outside interface goes down, (the internet connection is a 
wireless connection and in inclement weather the connection is 
unavailable for some time). nobody on the internal network is able to 
even see the server let alone the shares. I am stumped on this one, any 
ideas.
