Inbound vs Outbound traffic and activating IPv6 on my router


I recently activated IPv6 on my router per my understanding of my ISP configuration (I called the tech support and they had zero clue what I was asking about, so I looked it up) and suddenly on my Relay via Nyx, I have thousands of inbound connections that I never had before!

Yet, strangely, a significantly fewer number of outbound traffic.

I have spent the last day or so trying to get my relay to recognize the IPv6 and get the OK from running…

ping6 -c2 2001:858:2:2:aabb:0:563b:1526 && ping6 -c2 2620:13:4000:6000::1000:118 && ping6 -c2 2001:67c:289c::9 && ping6 -c2 2001:678:558:1000::244 && ping6 -c2 2607:8500:154::3 && ping6 -c2 2001:638:a000:4140::ffff:189 && echo OK.

Which tells me the relay can do the IPv6 thing, but that’s another post altogether.

My main question for this post is this: Why so many inbound suddenly when I never had any before turning on IPv6 on my router, and why is the number of outbound traffic not equal to inbound?


Not sure if forum bumps are allowed, but here is a friendly bump.

Hello @Koji,

The tor network is having a major DDoS attack since a few months, you may have thousands of connections that are inbound of your relay. Its a consequence of the DDoS, relays have a lot of connections which overload them. For me, the IPv6 isnt the problem.
You can put a limit of connections in the torrc config if it blocks yours with ConnLimit parameter.
