Repetitive Tasks: using if..then inside a loop


I thought I was getting pretty good with Bash but this problem is stumping me. Any suggestions would be greatly appreciated. I've written a firewall script that uses a lot of functions. The variables are read into the script from another .conf file earlier on in the code. Most of these variables are either set as "ON", "OFF", or as an IP address. To date, I've written out a conditional statement for each service. Here is an example of two of them:


if [ $FTP = "ON" ]; then
FTP_WAN
else
if [ "$FTP" != "OFF" ]; then
FTP_PORT_FORWARDING
fi
fi

if [ $SSH = "ON" ]; then
SSH_WAN
else
if [ "$SSH" != "OFF" ]; then
SSH_PORT_FORWARDING
fi
fi


I'd like to figure out a way to make one conditional statement inside a loop where the $SSH or $FTP variables are replaced for each variable corresponding to a service.

I'd thought something like:


$SERVICES=SSH,FTP

for VAR in $SERVICES; do

if [ $VAR = "ON" ]; then
$VAR_WAN
else
if [ "$VAR" != "OFF" ]; then
$VAR_PORT_FORWARDING
fi
fi

done


But no variation I've tried seems to work. I want it to
input the variable, like SSH, and then read the value
of SSH inside the conditional statement. Am I missing
some brackets somewhere or anything else?

Thanks.

gnome-ssh-askpass

GNOME-SSH-ASKPASS(1)					      General Commands Manual					      GNOME-SSH-ASKPASS(1)

NAME

       gnome-ssh-askpass - prompts a user for a passphrase using GNOME

SYNOPSIS

       gnome-ssh-askpass

DESCRIPTION

       gnome-ssh-askpass  is  a GNOME-based passphrase dialog for use with OpenSSH.  It is intended to be called by the ssh-add(1) program and not
       invoked directly.  It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display
       is  available).	This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro-
       grams, for example.

       In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass.

ENVIRONMENT VARIABLES

       The following environment variables are recognized:

       GNOME_SSH_ASKPASS_GRAB_SERVER
	      Causes gnome-ssh-askpass to grab the X server before asking for a passphrase.

       GNOME_SSH_ASKPASS_GRAB_POINTER
	      Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase.

       Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab().
