Do you know which version you started seeing this problem? Any reason why you don't roll back? I have been using 6.38.7 with no known ospf issues...OSPF issues has plagued recent versions of RouterOS.
Which version was this introduced? I have like 500 routers running ospf and don't want to run into it : )No, it is not in this version yet.Has the "ospf - fixed OSPF v2 and v3 neighbor election" included in rc been added silently?
this sounds correct and usable, however wouldn't the implicit rule at the end of the chain just accept them anyhow?add chain=input/forward protocol=tcp fragment=yes action=accept
