I have user that can successfully VPN into firewall A.
There is site to site vpn established successfully between firewall A and firewall B.
User is trying to reach a subnet on firewall B.
The traffic was sent from firewall A with a certain number of bytes but received with 0 bytes.
Firewall B did not receive the traffic.
Static route was also configured correctly.
What is the possible issue?

Hi @BusinessUser.,
Please run the following debug flow to see if the traffic is being dropped:
di deb disable
di deb res
diagnose debug flow filter clear
di deb flow filter saddr x.x.x.x <<<Source IP
di deb flow filter daddr x.x.x.x <<<Destination IP
diagnose debug flow show function-name enable
di deb flow show iprope en
diagnose debug console timestamp enable
diagnose debug flow trace start 500
diagnose debug enable
Regards,
Just try to NAT your traffic in the policy. Not a necessarily a final solution but just try to see.
