How to let these ports listen only on one device?

[Roland Haeder]

Hello together,

I run Tahoe-LAFS on my local network on all my computers (because of
their storage capacity). This also includes Laptops (Debian, Gentoo)
with WiFi cards.

I then run batman-adv to let the laptops mesh a little. I have now found
1 Tahoe-LAFS port open to 0.0.0.0 which means they are accessible from
outside through my WiFi cards.

Of course, I can turn them off but then I cannot mesh. :)

So here are the ports:

laptop ~ # netstat -lnp|grep "0 0.0.0.0:"
tcp        0      0 0.0.0.0:8097            0.0.0.0:*
LISTEN      12239/python2.7
laptop ~ #

Is there a way to only let it open to my LAN (cable) network, e.g. a
tweak in config file?

Best regards,
Roland
