My pfsense LAN clients cannot ping the wan inteface

hello first time interacting with firewalls, so i wanted to use pfsense in vmware, and putting it in gns3 i been trying to set up pfsense firewall for the first time, i used R2 to simulate a WAN,and i added an ftp server(also vmware win7) , who i wanted to access from the win7 vm, and then block the access using the firewall,but LAN and WAN wont ping

So i want to know what to do to make it work
i am utterly new to pfsense
and also new to Firewalls and how they function
so for starters i would like to access the FTP server from the WIN7
and how can i block it from accessing it
but win7 cant even ping e0
i have deactivated hardware checksum
thank you all
