Web15 Aug 2024 · 2. RE: SRX VPN Tunnel Change MTU size. what you can try is setting the tcp-mss on the vpn to somthing like 1350. You can also try sending over packets with a max size of 1500 over the vpn and lower the value until you reach the size that will "pass" the vpn. You can use the max packet size then to set that as the max for the ipsec-vpn mss.

WebEssentially, the MSS is equal to MTU minus the size of a TCP header and an IP header: MTU - (TCP header + IP header) = MSS. One of the key differences between MTU and MSS is that if a packet exceeds a device's MTU, it is broken up into smaller pieces, or "fragmented." In contrast, if a packet exceeds the MSS, it is dropped and not delivered. WebThe TCP maximum segment size (MSS) is the maximum amount of data that can be sent in a TCP segment. The MSS is the MTU size of the interface minus the 20 byte IP header and 20 byte TCP header. By reducing the TCP MSS, you can effectively reduce the MTU size of the packet. The TCP MSS can be configured in a firewall policy, or directly on an ...
