Hi All,

Having some issues with a new-ish USG Pro 4. Changes made in the controller for DHCP and Default gateway is not being saved to router. I've contacted Unifi and they've simply told me they cannot reproduce the issue and closed my case, even though people are experiencing the same issue on their forums.

I did a quick check through ssh:

admin@ubnt:~$ show configuration commands | grep dhcp-server
set service dhcp-server disabled false
set service dhcp-server hostfile-update disable
set service dhcp-server shared-network-name LAN_192.168.1.0-24 authoritative disable
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 lease 86400
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 start 192.168.1.100 stop 192.168.1.253
set service dhcp-server static-arp disable
set service dhcp-server use-dnsmasq disable



So gateway and DNS server are not being advertised even though the details are in the controller under networks-> Lan-> Edit. I tried both manual and automatic configuration of dns and gateway, both will not update the USG settings. Also tried to re-adopt and nothing.

Using the following:

configure
set service dhcp-server shared-network-name LAN_192.168.1.0-24 authoritative enable
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 default-router 192.168.1.1
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 dns-server 192.168.1.1
commit
save
exit


Now the USG works as intended and shows the following:

admin@ubnt:~$ show configuration commands | grep dhcp-server
set service dhcp-server disabled false
set service dhcp-server hostfile-update disable
set service dhcp-server shared-network-name LAN_192.168.1.0-24 authoritative enable
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 default-router 192.168.1.1
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 dns-server 192.168.1.1
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 lease 86400
set service dhcp-server shared-network-name LAN_192.168.1.0-24 subnet 192.168.1.0/24 start 192.168.1.100 stop 192.168.1.253
set service dhcp-server static-arp disable
set service dhcp-server use-dnsmasq disable

So issue with this is that every time I make an update to something in the controller, the USG loses its settings and have to re-ssh and configure again. As Ubiquiti is being extremely unhelpful in the matter, is there anyway to make the changes persistent, without the possibility of having any issues later on when upgrading firmware and software?
