Disable tunnel acceleration for GRE, VXLAN, and GTP-U
tunnels to troubleshoot.
By default, supported firewalls perform tunnel
acceleration to improve performance and throughput for traffic going
through GRE tunnels, VXLAN tunnels, and GTP-U tunnels. Tunnel acceleration
provides hardware offloading to reduce the time it takes to perform
flow lookups and allows the tunnel traffic to be distributed more
efficiently based on the inner traffic.
GRE and VXLAN tunnel
acceleration is supported on PA-3200 Series firewalls and PA-7000
Series firewalls with PA-7000-100G-NPC-A and PA-7050-SMC-B or PA-7080-SMC-B.
You can disable tunnel acceleration to troubleshoot. When you disable
tunnel acceleration, you are doing so for GRE, VXLAN, and GTP-U
