I have a computer under my TV that doubles as a squeezebox/subsonic/file/ssh/git server.
The layout is:
- I have a home router connected to the internet
- I have Turris connected to the router
- Everything else connects over WIFI to the Turris.
However Often I cannot SSH (or ping) over from my laptop to my TV computer, also my Sqeezebox seems to spend as long disconected from the server as it does connected. I have also noted that if I ssh over the the Turris I can ping/SSH the TV computer. It also seems that it never fails to connect to TV Computer if I connect my laptop over OpenVPN remotely.
I’ve investigated this a bit more this morning and I found that deleting the bottom route from my routing tables seems to fix the problem. While this may be co-incidence, it appears to make sense (at least at my level of understanding)…
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default gateway 0.0.0.0 UG 600 0 0 wlp1s0
link-local 0.0.0.0 255.255.0.0 U 1000 0 0 wlp1s0
172.17.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0
172.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-67ead90c26e6
192.168.12.0 0.0.0.0 255.255.255.0 U 600 0 0 wlp1s0
The routes must come at least partially from the Turris? I don’t seem to have these issues on other networks, it is a very standard Ubuntu install (just with docker extra)
This is not a new problem, it’s has not worked correctly for a very long time. Any advice on fixing this, whether that means making the route never coming back or explaining to me what the real problem is/might be would be very welcome.

Thanks
