Hi I am a noob when it comes setting up pfsense or networks and trying to learn. but i can't find much info on running pfsense behind a router that gives me a clear setup.
Running pfsense 2.3 on an old PC with 1 Wan and 1LAN port. Wan Port to the ADSL Router (not plugged into the its WAN port) like this:
ADSL modem/router >>>>> pfsense pc/dhcp >>>> Switch >>>> PCs
when i 1st connected everything on a fresh install it all just worked, all the PCs behind pfsense could see the internet. now i dont know what ive done and a fresh reinstall has not helped. i can get the PCs behind pfsense to see a DNS. sigh
