Web20 dec. 2024 · Because the MTU of the GRE tunnel is 1476, the 1500-byte packet is broken into two IPv4 fragments of 1476 and 44 bytes, each in anticipation of the additional 24 byes of GRE header. The 24 bytes of GRE header is added to each IPv4 fragment. Now the fragments are 1500 (1476 + 24) and 68 (44 + 24) bytes each. Web13 feb. 2024 · PAN-OS® Administrator’s Guide. Networking.
