2- choose service you want to enable

3- choose what you need

4- select the interface connect to internet and disable stateful firewall

5- select the source ip that server will provide to client

6- create ip range for client – if we use automatic we don’t need to create it will choose from dhcp server

7- we choose to get the authenticate source from the vpn server, or we can choose from RADIUS server

8- finish enable vpn remote access server

MAKE L2TP INTERFACE

1- it is the same as the one we created above, but only a little configure to make it become L2TP interface

2- on security tab type the PRE-SHARED KEY phrase
