@dam034 said in Bind webGUI only to certain interfaces:
The pfsense machine WAN IP is private, and I'm now trying from another pc in the same LAN as pfsense's WAN interface.
Is there any mistake?
No mistake at all.
Look at your firewall rules.
The first rule is put in place 'automatically' when you check this option on the WAN interface.
Here it is :
0_1551249981391_1d0b3dca-7a30-4529-a723-1c0b7dbcce20-image.png
So, when this box is checked - yours is checked - local IP's like (192.168./16 10/8 etc) are blocked.
The counter in front of your first rule indicates it is blocking "something".
These must be your attempts to use your phone to connect to the GUI.
When you use your phone, you use some real WAN IP (an address IPv4 that is addressable on the Internet).
The connection comes in on your first router, probably the one your ISP gave to you, or some other upstream device.
This device NAT's to the pfSense WAN IP - and this IP is a "RFC 1918" class IP.
pfSense, according to your instructions, blocks these IP's.
Btw : before you ask : the second rule will not bother you, although it's a nice exercise to know who's triggering that rule ^^
