You do not say what network manager you are using. If you are using NM first 
write a shell script to mount and unmount your shares. Then do something like 
outlined below. Then learn to use google.

# /etc/NetworkManager/dispatcher.d/05-mnt-hshares                                             
# mount the shares I use at home when we connect                                              
#!/bin/sh                                                                                     
export LC_ALL=C                                                                               
if [ "$1" = "eth1" ]; then                                                                    
    if [ "$2" = "up" ]; then                                                                  
        SSID=`iwconfig $IFACE | awk -F\" '{print $2}'`                                        
#   unmount work shares                                                                       
        /root/bin/workUnNetStuff.sh                                                           
#   mount home shares                                                                         
        if [ "$SSID" = "fishnet" ]; then                                                      
            /root/bin/homeNetStuff.sh                                                         
        fi                                                                                    
#       /usr/sbin/vpnc

    if [ "$2" = "down" ]; then                                                                
        /root/bin/homeUnNetStuff.sh                                                           
#       /usr/sbin/vpnc-disconnect
