Site to Site VPN Issue .

We Have two offices one is Head Office we Call As Site A and the Other is Branch Office we Call as Site B.

TZ 500 wireless-AC this is Firewall Model in Site A {Head Office}

TZ 400 wireless-AC this is Firewall Model in Site B {Branch Office}

We Are Connecting regularly from Site A Server to Site B Server, Few Day Back Public IP Address has Changed in Site B, We also Changed the IP Address in the Site A Firewall.

When We Observed the VPN Tunnels in both Sites it's Showing UP and In the Active Tunnel List, it Shows up.

But When we Ping from Site A to Site B It's Showing Destination is unreachable.

But when We Ping From Site B to Site A it's Pinging.

Any One Please Help Me To Fix this Issue?

Thank You
