# a local socket. This is completely transparent to the
# user, and should generally be turned on. This directive
# is optional and can be removed for brevity.

# need any functional IP infrastructure like routers
# or DHCP servers, but will require that at least link-
# local IPv6 is enabled in your operating system, which
# should be enabled by default in almost any OS. See
# the Reticulum Manual for more configuration options.

# within the local broadcast domains of all local
# IP interfaces.
# Instead of specifying listen_ip, listen_port,
# forward_ip and forward_port, you can also bind
# to a specific network device like below.
# device = eth0
# port = 4242
# Assuming the eth0 device has the address
# 10.55.0.72/24, the above configuration would
