TS5-PoE config

howdy,
I dont know why but I am missing the line from A to B.
pB400 config,
Mesh RF 10.236.177.149/8
Lan 10.101.140.169/29
WAN DHCP ( from RPI4 10.1.1.2 )

SInce the pb400 has 1 eth, i made bridge from an RPI4, eth is 10.1.1.1/28 (dhcp to pb400) bridges to Wlan0 172.16.5.x to the internet router of 172.16.5.1
Which TS5 config is this? 2 LAN 2 NODE 1 WAN?


pb400 <>TS5port?
radio pc<>TS5port?
RPI4_bridge<>TS5port5

Thank you for your support.
