Hello again, as you know that nowadays there are lots of discussion about native/national software. The most controversial subject is about operational systems, especially about Pardus and Windows. Actually, I’m not a specialist on these topics so I try to say nothing 🙂 In addition to operational systems, we must consider other systems/solutions to exchange with free software solutions, such as office apps, engineering apps, graphic design apps and of course firewall solutions.
The last month, I looked at FortiGate solutions and I observed some example scenarios using virtual lab. In this post, I will write about pfSense solutions which is an alternative for FortiGate. Firstly, I must say that installation steps of pfSense are more complex than FortiGate steps 🙂 Maybe you know, all open-source projects has this problem to redirect you to technical support for earning money from you 🙂
When I met firewalls in last month, I liked them and I said that I would use this always, even at home 🙂 Now, I’m trying to discover them, and I liked pfSense.
Before we begin, let me summarize all steps;
- Install: Typical installation, follow the instructions.
- Configuration: There are lots of network cards/adapters on firewall devices and they are used to route packets. And firewall software manage these adapters to block or pass network packets. Administrator have to set adapters for WAN, LAN1, LAN2, LAN3 etc.
As you see, there are some options to move on. But first of all, we have to set the adapters for their tasks so we use (1) Assign Interfaces. I have 4 adapters for my demo example.
- WAN -> em0
- LAN -> em1
- Opt1 -> em2 (10.0.5.10, gateway for computers which are in this subnet)
- Opt2 -> em3 (10.0.6.10, gateway for computers which are in this subnet)
Now, after press “y” to proceed, we have to set IP addresses for these adapters. So we use (2) Set Interface IP adresses sub menu.
Now, let’s access to the GUI 🙂
You can try to explore “Firewall” menu and rules, I’ll write later about firewall rules 🙂
