WebTCP MSS for IPv6 in GRE over IPv4; MTU for IPv4 in an Ethernet VLAN over L2TPv3 over UDP. Header sizes for VXLAN, LISP, and WireGuard include UDP, and STT includes TCP, because these protocols never use any other L4 protocol.

WebDec 20, 2024 · The IPv4 packet size is 40 bytes larger (1500) than the MSS value (1460 bytes) in order to account for the TCP header (20 bytes) and the IPv4 header (20 bytes). You can adjust the MSS of TCP SYN packets with the ip tcp adjust-mss command. This syntax reduces the MSS value on TCP segments to 1460.
