https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196011 Bug ID: 196011 Summary: if_gre tunnel works without rebooting system only in any one direction (send or receive) Product: Base System Version: 10.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: kvas@bf.pstu.ru Making tunnels from my FreeBSD server to cisco works only in gif-mode ("tunnel mode ipip" in cisco terms). When tunnel was changed to gre-mode the situation becames strange. If tunnel only receiving or only sending packets (changing it with ipfw2 at FreeBSD and route priorities on cisco) it works great for hundreds of hours. If usage of gre-tunnel becames bi-directional then in some minutes (depends on load but not more then half-hour) the system reloads. After reload there is nothing was found in logs about the reason of reload. Bidirectional usage of gif-tunnel works fine. Unidirectional usage of gre-tunnel works fine to. But I need to make all 3 tunnels (or at least 2 of them) a gre-tunnels to be able to put "keepalive 1 3" in cisco configuration making it able to detect tunnel aliveness. I am using FreeBSD 10.1-Release (upgraded from 10.0) as router to connect LAN to 2 (some times to 3) internet providers. Each provider gives as one white IP (rtcom as PPPoE and saturn as /30 net in vlan). This functions works great. And over each provider my server have to make a tunnel to our head office. Previously it was done with cisco router and now I am trying to make this scheme using FreeBSD as a router. -- You are receiving this mail because: You are the assignee for the bug.
