Bridge 2 Networks with SRX5308 Help

I got it working.  Thanks to c3po2​ for the guided assistance..   In a nutshell here is what i did.  My brain was cramping for days with this.

The First Key, was properly setting up the VLAN's on Both Firewalls.  In the SRX5308, I created VLAN20 with the IP 172.16.10.1/29 located in Building A.  Building B TPLink ER605 I created VLAN20 with the IP 172.16.10.2/29.  The SRX5308 VLAN, has Inter-Vlan Routing box enabled. *Note - The Ubiquiti Nano 5ac Antenna is plugged into LAN 3 on the SRX5308.. NOT the Wan port.  Shown below are the settings for the VLAN (called CBBridge).   As you can see also, i only have Port 3 checked off, where the Antenna is plugged into.

Next the Routing on the SRX5308 shown Below.  The cavieat that i didn't figure out til i tried it, was the Gateway.  I kept thinking the 172.16.10.1 IP of the Vlan on the SEX5308 was the one to use, i was incorrect.  I had to use the 172.16.10.2 gateway, which is the IP of the VLAN on the TP Router in Building 2.  Before i figured that out, i was able to ping things using the internal diagnostics of both firewalls, but unable to get the Lan to ping (which the routes fixed).. Here is that config.

This is the routing i setup, which is a single static route for the people at building A to get to building B's Nas drive.

On Building B's side,  this is the setup. (TPLink ER605)

This is the static route i created on the TP Link so the Building A network can communicate to the Building B LAN thru what i called "UbiquitiBridge" VLAN.

As you can see, its routing all the 192.168.1.1 traffic thru 172.16.10.1 which is the gateway of the VLAN on the SRX5308 in Building A.

Now, all the machines that have mapped drives to the NAS Share at Building B are operating at full gigabit speed, and I am extremely happy.

Thanks to everyone for the help, and guidance.  I hope this can help others who need to do the same thing.

*Note - while i haven't yet gone on site to make sure both DHCP servers are not in any way messing with anything, i created a ALWAYS BLOCK rule on the SRX5308 to Block UDP port 67 from the IP range of the VLAN.*
