https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206721 jimp@pfsense.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jimp@pfsense.org --- Comment #10 from jimp@pfsense.org --- There does not appear to be a way to disable or override this behavior, even using supersede in the dhclient.conf doesn't let you turn it off or set an alternate value. My ISP sends a bogus MTU value of 576 which was ignored before, but now gets set and leads to major connectivity issues since the MTU should be 1500. The link bounces when the MTU is set as well, at least on e1000. I see dhclient was changed to help cope with that but it also affects other things that key off link up/down events. Any chance this can be reopened and the change backed out until it can be made optional, perhaps by a command line parameter to dhclient? This will probably impact a number of people unexpectedly on upgrade. -- You are receiving this mail because: You are on the CC list for the bug.
