Otherwise did you consider setting up your router with
devuan by hand putting all the pieces together. This will
be highly educative even if somewhat bumpy at the start.
I went this way and never regretted it and I've learned a lot.
Forget about the shiny web interfaces they aren't worth
the hassle, ssh is the way.
Once you understood how it works you wouldn't want
to go back, in the end a router is just one more computer
with a bunch a configuration files.
if you DIY you can add any feature you like or need:
firewall.....done
vpn.....done
dhcp....done
dns.....done
adblocking....done
ntp....done
suricata....done
hostapd....done
apcupsd....done
and so on...you name it you do it.
