I'd like to set up a firewall or tap between my router (Ubiquiti Edge) and our network.
I know I can monitor network traffic with our router but I'd like to experiment with setting up a firewall or tap to monitor all network traffic between the public ip router and our private ip
<-<ROUTER TO PUBLIC IP>---<FIREWALL OR TAP WITH 3 NICS>--<LAN 10.183.0.0/16>
I have hardware with a built in nic (1000) and a Cisco duel nic.
So if have 3 network ports that all are recognized using Centos 8.
I have never done anything like this.
Please throw me a bone.
Code: Select all
