Hi,
iptables has a nice feature to circumnvent broken Path MTU Discovery with TCP protocol: Maximum Segment Size clamping.
I can manually set the MSS to a fixed valued via CLI/GUI, which is okay in cases where PPPoE/PPPoA is used. However this approach does not cover all cases. In my IT career I found many sites/hosts with MTU lower than standard, with different MTUs, so having clamp-mss-to-pmtu iptables option is more a needed feature than a desirable one.
I know I can manually enable clamp-mss-to-pmtu using iptables directly, but I'm wondering if this is doable nowdays via CLI. I'm running and ERLite-3 w/ 1.9.0.
If it is not yet available, is there an ETA?
Thank you!
