The MTU reported by tcpdump seems to always be 12 bytes less than the MTU I set tun0 to. What do I do about it, though, to keep my connection flowing? The TCP/IP stack is supposed to probe routers by setting the don't fragment bit and watching for icmp packets and set the MTU in routing tables accordingly, but I get the feeling something is not working right here. Should I ask this question of freebsd-bugs? - -Tim -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use <http://www.pgp.com> iQA/AwUBOgLy5xJDu7xQsK72EQLJBwCg8aZgk+1iNGOiLvAu4F+68hrzocQAnjZk 89B1ApWDFhWWBzX606yb7lyr =CD4/ -----END PGP SIGNATURE----- To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
