Web11 ago 2024 · The current implementation of TCP MTU probing can considerably underestimate the MTU on lossy connections allowing the MSS to get down to 48. We have found that in almost all of these cases on our networks these paths can handle much larger MTUs meaning the connections are being artificially limited.
WebFor example, you might enable TCP MTU Probing in these cases: You have a slow PPPoE connection and require smaller packets to optimize performance. You want to make sure that clients on your network can access the Internet through a zero-route BOVPN tunnel on this Firebox even if the Path Maximum Transmission Unit (PMTU) discovery process … tcp_mtu_probing - INTEGER.
