I understand that RELENG_4 is at end of its life but ipnat/dummynet interaction further breakage between 4.10 and 4.11 (due to IPFilter 3.4.35 import) is, IMHO, not acceptable for FreeBSD, especially RELENG_4 which is a must in term of stability and release engineering. My workaround was to go back to RELENG_4_10 branch in src/sys/contrib/ipfilter. Given that *there are* patches in these PR, although we should admit these are not examples of long term solution, is there any chance to get this commited into RELENG_4 to assist this old good branch until its funeral ?
