I have been using a Linksys WRT3200ACM with OpenWRT for a WAP. This sat behind a Netgate 3100SG in a double NAT configuration. With my most recent network upgrade, however, I wanted to have a Wifi 6 capable wireless AP while still keeping my PFSense box as my main routing device and getting rid of the double NAT configuration. I did some research, and decided on the Unifi 6 Lite from Ubiquiti. I've successfully flashed OpenWRT to the device, as it was fairly quick and easy for a Linux user like me. I will make some contributions to the device page to make it better and easier to follow - especially for less experienced people. That being said, however, I mistakenly installed the snapshot version of OpenWRT, so I don't have LUCI. Also the current device page is rather hard to find: https://openwrt.org/toh/ubiquiti/unifi_6_lite, as the old device page is a dead link that shows up in search results more readily. It would be nice if it were more clear what versions of the OpenWRT firmware can be installed on this device when installing it for the first time too.
Anyway, my mistakes aside, the thing I need help with is that I do not have access to the Wide Area Network on this device so I cannot perform software upgrades with opkg and install LUCI or even SFTP. I don't know what my other options are; so I was hoping someone could help me get my WAN working in OpenWRT. Here is the current
config interface 'loopback' option device 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option packet_steering '1' option ula_prefix 'fdf3:705f:c47a::/48' config device option name 'br-lan' option type 'bridge' list ports 'lan' config interface 'lan' option device 'br-lan' option proto 'static' option ipaddr '192.168.57.2' option netmask '255.255.255.0' option ip6assign '60'
It is pretty much the default file that existed with the device. I only changed the IP Address to match my LAN subnet so that it wouldn't conflict with my PFSense box. Here, also, is the output of

Usually it's what I turn to to find networking issues, but this time it didn't help me. Also, my ISP is Google Fiber, and it doesn't support IPv6, so I tried to disable IPv6; but I was unsuccessful. Additionally, I've attempted to disable DHCP, I end up losing SSH access and have to reset it. I must be doing something wrong here. It could also be a problem with my PFSense configuration now that I think about it. I have that set up to assign the Unifi 6 Lite's MAC address to 192.168.57.2 permanently though. This device only has one port, so that's been my biggest problem when trying to configure it. I've messed with it for 3 days, but I got work to do; so any help would be appreciated.
