No. Linuxconf tries to parse the various configuration files to work out
what the current settings are. In general, I think it is safer to use
linuxconf all the time, just to keep everything sane.
In this case, though, linuxconf (on RH6.2) will change the
/etc/sysctl.conf file. If you do the same thing, I would recommend
altering the comment before the line that sets up ip_forwarding (it is a
particularly *stupid* comment, imho, since it says what the default
setting does and if you change that setting without altering the
comment, you are left wondering whether 1 means "enabled" or
"disabled").
Cheers,
Malcolm
