Does not work when an interface has multiple IP addresses

Open tomrittervg opened this issue 4 years ago • 1 comments

I have a linux box as my router; it sits under a comcast modem/router - but all devices are under the linux box. eno1 is the 'external' nic; enp2s0 is the internal. There are a bunch of static ips assigned for the internal nic for each subnet.

This seyup however does not seem to be supported bby static_upnp, attempting to reregister multicast fails with address in use. (I added the 'Attempting to reregister' log line at the beginning of the loop that has ''Reregistering multicast'):

2021-12-27 21:37:40,956 INFO    UPnPServiceResponder util.py:setup_sockets:82 - Attempting to regester multicast for: 239.255.255.250: 10.1.1.1
Traceback (most recent call last):

    multi_sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)
OSError: [Errno 98] Address already in use

I don't know if my setup is weird and wrong and I should do something different; or if there is a way to hack around this to make it work...

It seems like specifying only the 10.0.0.1 IP address may have let me work around this....
