--82I3+IH0IqGh5yIs Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi all, first of all, could you please cc any replies to me ? (I'm not on this list). Last time I checked (around fbsd4.3) , I was unable to set the mtu of a gif device higher then 1280. I just cvs'ed from 4.4 to 4.5, and saw that i was able to set the mtu of the gif device to 1500 (and saw that my 4.4 box could do the same). The weird thing is, though, that since i've upgraded to 4.5, ssh connections from my irix and bsd box in my network (which have public ip's tunneled from work) die spontaniously. They either die when i give it a lot of input, or when i idle for a bit. It smells like a mtu problem to me, but i can't find the problem. When i ssh directly from my router trough the tunnel to work, i get a stable connection, so i figured the home-router itself is the source of the problem. Set up is like this: colo (gif with mtu 1500) -> gif tunnel -> home-router (gif with mtu 1500/ interfaces with mtu 1500) -> irix box (mtu 1200) / bsd box (mtu 1500). Both the irix and bsd box have the problem. The problem was also occuring when the mtu of both gif devices were set to 1280. It all started when i upgraded my home router from 4.4 to 4.5.=20 Any suggestions are welcome.=20 With regards, Bart=20 --=20 Bart Matthaei bart@dreamflow.nl=20 Support wildlife -- vote for an orgy. --82I3+IH0IqGh5yIs Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE8Yuuygcc6pR+tCegRAn7pAJ9e4aQuSzLlen+11Qrq6C1EVQZzPwCg1DqV 4BsVZOHXJRgbEpxf5jM7Ov4= =x6zg -----END PGP SIGNATURE----- --82I3+IH0IqGh5yIs-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
