What I am trying to achieve is to have the RPi 3B+ connected to a wall LAN port via cable to it's own LAN port as a WAN(and set to DHCP Client), and the WiFi, as WLAN(set to Static IP), is how I would be connecting to the router(no surprises, unless I get a USB-Ethernet adapter). Having them separate gives me no internet connection on the devices connected via WiFi, but if I bridge the WLAN(or LAN, as it is called in what I have) to the WAN(which is the single LAN port the Pi has), then I get an internet connection, but I lose access to the router configuration page and am unable to SSH into the router unless I disconnect the Pi from the wall LAN port and connect it directly to my laptop with IP settings set to manual. Am I doing something wrong?
Image used is the snapshot, since the stable release does not work.
I used part of this video as a reference. Time it starts at is what the config page looks like. Of course, if needed I will post pics and text files.
I'd like to ask: I keep getting 'Unsaved Changes'. How do I get the changes to be really applied?
Or should I restart with a more up-to-date snapshot for a cleaner slate to work on?
I suppose the following is what the setup should look like(whether it is saved and applied is a different thing)
Interfaces:
I noticed that for some reason the eth0 is shown as offline, even if an Ethernet cable is plugged in.
By any chance, do you receive a BIG WARNING that the settings break something (i.e. connectivity to the GUI), with and option to APPLY ANYWAY in a RED button?
If I see the 'Applying changes' timer time out, then I do see that alert. Other than that, since I do not see the timer time out, 'Changes applied' pops up, but sometimes there are still unapplied changes.
How do I set up the WAN part of the router? Read this post where eth0 needs to be bridged to get an IP in DHCP client mode. Should I try that out? What else am I missing?
EDIT: Seems like what I was missing was bridging WAN, as shown below: Both WAN and LAN are now shown to be connected.
These are the settings I have for the firewall:
Deviated a bit from what @lleachii posted in here, would like guidance on what the differences would be if possible.
