Setting up a UPnP server
------------------------
In order to share the connectivity with others, it is necessary for re6stnet
port (as specified by ``--pp`` option and default to `1194`) to be reachable
from outside. If the node has a public IPv4 address, then this is not
necessary, otherwise a UPnP server should be set up on the gateway.
You can check the connectivity with other re6st nodes of the network with
``netstat -tn | grep 1194``.
Sample configuration file for `miniupnpd`::
ext_ifname=ppp0
listening_ip=eth0
clean_ruleset_interval=600
allow 1024-65535 192.168.0.0/24 1024-65535
deny 0-65535 0.0.0.0/0 0-65535
After restarting ``re6stnet`` service on the clients within the LAN, you can
either check ``/var/log/re6stnet.log`` or the ``iptables`` ``NAT`` table to
see that the port ``1194`` is properly redirected, for example::
# iptables -t nat -L -nv
[...]
