NSecurity 8 - Multi-internal networks

NethSecurity
1

@giacomo

I have tested NethSercurity in the past and ran it as my main firewall for a little while. All of these uses were with 1 WAN and 1 LAN configuration.

I have a use case and I know I can test out to get the answer, but I don’t currently have another device with multiple nic freed up for test at the moment. It should be a pretty easy question to quickly answer, it will also help anyone else with this question that might be looking to do the same configuration.

Does NethSecurity allow for multiple internal networks. For instance. If I have 4 network cards on my device.

NIC_1 = WAN. (Internet / Public IP or DHCP)
NIC_2 = LAN1/OPT1 (network 1 ex: 192.168.40.1 / DHCP 192.168.40.200–192.168.40.254)
NIC_3 = LAN2/OPT2 (network 2 ex: 192.168.50.1 / DHCP 192.168.50.200–192.168.50.254)
NIC_4 = LAN3/OPT3 (network 3 ex: 192.168.60.1 / DHCP 192.168.60.200–192.168.60.254)

Is this possible? I appreciate the help and guidance.

Of course is possible.
You can create how many networks you like, each one with a different zone, or all with the same zone.
It’s just up to you how to organize them.

Okay. I see that information here in the manual.

https://docs.nethsecurity.org/en/latest/network.html

Every network interface has a specific zone which determines its behavior. A basic network setup for a router typically includes a minimum of two interfaces, namely LAN (Local Area Network) and WAN (Wide Area Network):

All configured network interfaces are listed at the top of the page. Each interface is displayed with its name and the assigned firewall zone. This section offers an immediate overview of the current configurations, allowing users to quickly see which networks are already set up and associated with specific security zones.

Thanks for the quick response!
