EOIP Tunnel Overhead
1500 <-- Starting MTU
- 20 <-- Subtract 20 bytes for the IP headers (EoIP)
- 8 <-- Subtract GRE protocol header (EoIP)
- 14 <-- Subtract the encapsulated Ethernet header (sans checksum)

How Calculate Best mss by mtu size
MSS = MTU – sizeof(TCPHDR) – sizeof(IPHDR)”
MSS = MTU – 20(IP header) – 20(TCP Header) = 1460

For MTU 1500 MSS1460
MSS (maximum segment size) typ. MTU-40B (TCP/IP header)
