![]() OPNsense has this file, but you cannot edit it directly in shell, it works but not after reboot. You can create your file in PFsense, default did not have this file. After google it, some call it software laser, and the solution is add a blacklist in this file:Īccording to some source this should be fixed in 2021 but I still having this problem.Ĭhange this file in OPNsense and PFsense is different, it caused me hour to found out. And then found some internal subnet IP traffic flooding. I noticed the flood in ZT interface, so I use packet capture to see what is those flood. ![]() at first I thought it was some OSPF settings, but I was wrong, wasted many hours here, so don’t want you guys repeat my steps. I kept monitor OSPF and found OPSF flap every 2-3 mins. But the real world is challenging.Īfter everything is setup ( I setup 3 nodes test with OPSF), I did a ping test, first 2 min is good, but after 2 mins, packet loss start showing up, then a few mins, its back to normal. So basically, installation and setup is pretty easy. Setup OSPF, its easy and straight forward. You may need to aware that Ospf has its own protocol, not TCP nor UDP. Then join you network (ZT bridge selected), add a allow all firewall rule for the interface, then begin your test.
