<span>Hi,<br>
</span>
<div><br>
</div>
<div>I am using WireGuard on a Raspberry Pi 3 B+ with Raspbian
Stretch and 4.14.98-v7+ kernel.<br>
</div>
<div>Now this works great for me and is very efficient, however I
tried to add a lot of routes on one of the "spoke/client" nodes,
517 routes to be exact.<br>
</div>
<div>If I do this, WireGuard stops working, tcpdump shows the
traffic being sent out the wg0 interface but never actually
being processed by wireguard, meaning the encapsulated packet to
the "hub" never leaves.<br>
</div>
<div><br>
</div>
<div>So I tried doing this with wg instead of wg-quick and this
works fine until I actually add a lot of the routes to the
routing table, the sweet spot seems to be 384. If 383 routes are
present in the routing table, wg will still work but if I add
one more, all previously working ones dont anymore, if I reduce
it again to <=383 then it starts working again. wg itself
doesnt mind having all those routes (wg show) but I wonder if it
tries to read the routing table as well for some reason?<br>
</div>
<div><br>
</div>
<div>Appreciate any insight/help on this, thanks.<br>
</div>

<p>did you tried using dynamic routing ? or it can't be applied ? I
have 262 routes available so can't confirm if dynamic routing will
work</p>
