Hello. I have an issue that is probably my own doing. My network is currently setup as follows.
Cable modem connected to the machine running IPFire (red - Class A).
IPFire connected to my home router (Green - Class B) and I have it assigning DHCP as 172.16.0.1 and the router is 172.16.0.3.
The router then connects to all devices on my network and hands out class C addresses.
I am currently blocking a specific outbound port from my green zone, and that rule is doing its job well. The problem is that I would like to know what devices are sending the outbound traffic on this port that I have forbidden. The logs do show that the traffic is being blocked, but it shows the source address as the routers class B address (172.16.0.3) instead of the IP of the devices (192.168.0.X).
Thanks for giving this a read.
