I have a 40F and want to use it for websecurity. At the moment I use a PfSense firewall with 2 internet connections and a 4G backup. Because I don't want to configure everything new at this time (homeoffices, second branch connected via Wifi, Vlans etc...) I only want to secure the traffic to our terminal server as everybody uses this server for webbrowsing.
TerminalServer is 192.168.100.2
PfSense is 192.168.100.169.
I set the Lan address of the FG to 192.168.100.168, set a route 0.0.0.0 to pfsense (192.168.100.169) and changed the gateway on the server to .168. This works for outgoing traffic, but not for incoming traffic. I also created on the pfSense a default route for 192.168.100.2 -> 192.168.100.168. But this did not help.
I think segmenting the subnet would be an option, but .1 is taken and connot be changed, alsochangeing the address of the TS would be a lot of work.
Can anybody tell me if it is possible what I want to do and how? I know this is not best practice and I should replace pfSense with FG and that is what I want to do in the long term, but for now I don't have the time to configure everything.
