Setup pfsense in GNS3

[asythehekes]

Hello, im new here and also i have no knowledge on how to setup a firewall. Im having a problem where i didnt know how to or what ip should i configure in my topology for pfsense. In my topology there is no connection for internet just a LAN topology, can refer to my screenshot. So i manage to configure and setup for lan interface only but for WAN i dont know and my hosts inside the network couldnt go out. Im student and still learning hope can get some helps and guidance here thanks :)!

You should be able to emulate the connectivity that PFsense provides by configuring a router with NAT enabled on the external interface (e0).

However, you will need to change the subnet on the internal interface (e1).
