Hi all,
I was playing with the RP Filter setting, between strict and loose while switching from single to multi-wan and I seemed to notice that the switch took effect only after router reboot.
Could any of you confirm such behavior or is it suppose to work right after the setting has changed ?
Thanks, Armando
I didn’t look much into it, but I did see it in the past. I don’t remember if it’s documented somewhere or not.
Thanks for reply.
I was checking in the forum as well the wiki, but couldn’t find any indication that reboot was needed.
However as I have a script to switch from single/dual WAN, when I checked RPF=strict and I was set to dual-wan, initially things worked fine, but after rebooting the router I have started to see some connection being broken. Then switching to single-wan made things to work again and this led me to the conclusion that reboot have activated RPF=strict.
Now I have added the selection of strict/loose in the same script where I manage single/dual wan, but it might not do much if reboot is needed anyway to take effect.
I will do some more test, but I hoped reboot was not needed.
I was trying to implement a very simple routing-mark mangle rule and IT. WOULD. NOT. WORK.
The packets were getting dropped between prerouting and forward despite a viable route… simples… rp-filter=none… or not.
Having spent a couple of hours and quite a bit of nerves trying to troubleshot this, in the end all it took was a reboot to clear out the rp-filter.
Mikrotik, put that in the manual please!
