LuCI openwrt-19.07 branch (git-21.044.30835-34e0d65)
OpenWrt 19.07.7 r11306-c4a6851c72
I created a new network called `whatever`. It is neither part of `lan` nor `br-lan`.
In dropbear I restricted
→ System → Administration → SSH Access → Interface: "lan" (Listen only on the given interface or, if unspecified, on all)
(saved and rebootet)
I would assume that only devices from network `lan` can reach OpenWrt via SSH but also the network `whatever` can reach it. Is my assumption incorrect?
In the end I restricted it with firewall rules but for me this setting is irritating.
I also tried to use `br-lan` but that is not selectable via Luci and via ssh it gives an error...
option Port '22'
option Interface 'br-lan'
option PasswordAuth 'off'
error: interface br-lan has no physdev or physdev has no suitable ip
