Issue Description

As shown in Figure, network A and network B connect to the Internet through USG5300 A and USG5300 B respectively. The network environment is as follows:

Network A is on the network segment of This network connects to USG5300 A through GigabitEthernet 0/0/1.
Network B is on the network segment of This network connects to USG5300 B through GigabitEthernet 0/0/1.
Routes between USG5300 A and USG5300 B are available.

But pay attention

I used ADSL modem instead of router

You should replace Adsl modem by router or any layer 3 Device

Root Cause

ADSL Modem Support NAT so it can support routing between two firewall
