Hello Everybody,
I have an SRX in transparent mode, and i configured the two zones trust and untrust and all the polices to allow everything.
I have irb.0 which is in VLAN 3 and has an IP of 172.16.4.254. Devices that are connected to the SRX are able to ping each other. however, i can't ping from the SRX(172.16.4.254) any other devices and vice versa.
From the srx if i ping 172.16.4.1 it will not work and even if i do:
root# run show security flow session source-prefix 172.16.4.1 . it doesn't show anything even though that 172.16.4.1 is continuously pinging 172.16.4.41
below is the SRX config:
.
root# show
