@Gertjan said in pfSense behind pfSense - Not getting WAN IP from PFS1:
edit : and if this doesn't work, then you have to place a smart switch between PS1 and PS2. Split out the VLAN ID from PS1 out on this switch, and connect the assigned port to the pfSense 2 WAN.
I have several managed switchs and PFS2 was connected to one of the ports on one of the switches, which was configured with that VLAN-id. When I said I could ping the PFS1 IP address but nothing beyond, I assumed that it will be understood that internal networking was setup okay.
BTW, in the 7th post, I posted the reason for not working in the first place and then it started working as expected after the reboot, then it becomes very obvious that VLAN, tagging, managed switch etc. weren't the issue at all.
The question was why PFS1 couldn't provide an IP to PFS2 in the first place, via DHCP.
