https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D269770 --- Comment #7 from Eugene Grosbein <eugen@freebsd.org> --- (In reply to Peter Much from comment #6) > the logic when and how this happens is unintellegible In case of ipfw nat: 1) When "ipfw nat" rule processes packets in-kernel, a packet is passed to ipfw_nat_ptr() that points to ipfw_nat() function in sys/netpfil/ipfw/ip_fw_nat.c 2) ipfw_nat() can call LibAliasOut(), LibAliasOutTry() or LibAliasIn(). 2.1) LibAliasIn() calls LibAliasInLocked(). 2.2) LibAliasOut() and LibAliasOutTry() call LibAliasOutLocked() than can c= all LibAliasInLocked(), too. 3) So we end up in LibAliasInLocked() or LibAliasOutLocked() and both call HouseKeeping() function sometimes (not every time) calls CleanupLink(la, &l= nk, 0) to remove expired links but it is not supposed to touch permanent links = we have configured for port forwarding. --=20 You are receiving this mail because: You are the assignee for the bug.=
