Default pfSense hostname is external IP?

Hi,
I have a pfSense firewall my school, with multi WANs, multi LANs.

WAN_1: DHCP
WAN_2: static IP (11.22.33.44 - my ISP static IP)
–--------------
LAN_1: static IP (192.168.0.1)
LAN_2: static IP (192.168.1.1)

In General Setup hostname is "pfsense", domain is "local.lan".
I use DNS resolver (this is default).

The pfSense automatically generated this file "/var/unbound/host_entries.conf":


local-zone: "local.lan." transparent
...
local-data-ptr: "11.22.33.44 pfsense.local.lan"   # THIS IS MY EXTERNAL IP
local-data: "pfsense.local.lan. A 11.22.33.44"    #

The ARP table also shows:


WAN_2  11.22.33.44   pfsense.local.lan
LAN_1    192.168.0.1

How can I set the system hostname is my LAN ip?
The DNS resolver "Host overrides" makes a plus entry, this is not a solution.

Thanks!

Sorry,

I did not find the setting for this in pfSense. I think pfSense when installing, the pfSense the second interfaces address put the/etc/hosts fileautomatically. (My second interface is WAN_2). The unbound (DNS Resolver) read datas from this file and write this information into the```
/etc/unbound/host_entries.conf


I checked the DNS Resolver -> Advanced Settings -> Disable Auto-added Host Entries, and the host_entries.conf file does not contain this information now. I have manually entered these the DNS Resolver -> Custom options:

server:
local-zone: "local.lan." transparent
...
local-data-ptr: "192.168.0.1 pfsense.local.lan" # CHANGED IP MY LAN_1 ADDRESS
local-data: "pfsense.local.lan. 192.168.0.1" #


In the ARP table is show now:

interface IP address Hostname
WAN_2 11.22.33.44 router.example.com # extarnal ip, my external domain
LAN_1 192.168.0.1 pfsense.lan.home # internal ip, domain


This working  ;)
