Trial and error: The magic number for the payload length is 1400. Anything exceeding that terminates the connection. (Thus, the interface MTU needs to be set to 1395.)
One more question: Why does pppd set the interface MTU to 1412 in the first place, when it is called with "mtu 1200 mru 1500" in its command line? -- pppd sends packets exceeding MTU https://bugs.launchpad.net/bugs/317567 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
