beschulz/asio_service_discovery

Components for service discovery via udp multicasting. It's using boost::asio for async networking. It's non-blocking and non-locking.

asio_service_discovery's Issues

Discoverer and Announcer do not see each other

Hi, first of all, congrats for your nice library. I'm testing it and it works fine in most cases, but I have a special case that seems no to be working with.

See I have a laptop that is connected to inet using wifi, and to a raspberry pi by ethernet. The laptop is sharing the inet connection to the raspberry using the cable.

The raspberry has the ip 10.42.0.240 and I can connect via ssh without problems. However, theyannouncer/discoverer is not working.
Below is the ifconfig of the raspberry and laptop. Any ideas???

Thanks in advance
