Trace route repeating same hop
-
Not sure what I broke... so, was looking for alittle help... when I do a trace route (windows or linux) I get my router as the 1st hop...but then the rest of the hops are all the same:
Any ideas?

Routing loop probably. You added a default route via something that isn't the WAN?
If you have multiple gateways on that system make sure the WAN is set as the default v4 gateway in System > Routing > Gateways. If it's set to auto it may have chosen another gateway if the WAN went down.
Except the it appears to be looping at the Google end. Not much you can do about that if so.

That's actually the one spot I did check... And the IPV4 DEFAULT gateway is the WAN.
Ipv6 works correctly, btw.
Also really doesn't matter what I do a traceroute to... The pattern is the same.

You just get loops all showing the target IP? How exactly are you running traceroute?
-
Ah, are you running outbound limiters for FQ-CoDel?

YESSSSSSSS! That's it... I did setup the outbound limiters for FQ-CoDel!
Is this a side effect? bug? normal behaviour? Correctable?
-
It's a side effect I guess you could best call it. You need to add the two floating firewall rules shown here to bypass the limiters for traceroute and ping:

@stephenw10 Thank you! :-) I haven't tried the step just yet... family time. I'll get to it over the next couple of days.
