My default gateway won't stick

[leonard kleinow]

It seems that my default gateway goes away every time I logout.
I log on as root, type "route add default 141.211.204.1 1", and then
everything is peachy.  But when I log out and log back in again,
then try to telnet anywhere, I get "Network is unreachable." and must
add the default gateway again.
 
What file is the route command referencing? How can I make the add command
"stick"?
