Block Access To Admin Gui Question.
-
Hi,
I want to restrict access to the Admin GUI from the UNTRUSTED network. The way I have it per below seems to be working fine but then I saw the PFSense docuemnt link below and not sure if I should change it to that way. Basically my way just drops all traffic from UNTRUSTED net to the Firewall.
Is the way I have it robust and OK from a security perspective of should I go with the methods outlined in the document below? Thank you!
My setup has WAN, LAN and UNTRUSTED networks:
LAN = 192.168.29.1
UNTRUSTED = 192.168.30.1Current Setup:
I setup a BLOCK rule on the UNTRUSTED network:
Action = Block
Interface = UNTRUSTED
Addres Family = IPV4
Protocol = Any
Source = UNTRUSTED net
Destination = This firewall (self)PFSense Document:

Depends on what you are trying to do. The way you have it will block any device on the UNTRUSTED network from accessing anything on the firewall. That means if the pfsense is telling devices on the UNTRUSTED network it is their DNS server they will not be able to resolve IPs, or ping pfsense for debugging, or send any other traffic directly to pfsense.

Thanks. I thought about that just after I hit the post button! Would it be OK to add rule above this rule to allow the DNS to pass through?

@tr997 If your goal is to only block devices on the UNTRUSTED network from accessing the administrative features of pfsesse. They it may be better to specify a protocol of TCP and destination ports (usually ports 80 and/or 443 for the webpage and port 22 for ssh).

@tr997 Yes, adding a rule above to allow DNS and whatever other services you want to allow the UNTRUSTED network to access will also work.

@hieroglyph Thanks. You've answered my questions and I see what you mean about blocking the TCP admin ports.
