hello,

we found a problem in using updcast in a context of multi-routers when the rdv-addr is not multicast.

Indeed, in this case, the multicast ttl must be greater than 1 (--ttl). But it is only assign during the processing of rdv-addr and only if rdv-addr is a multicast IP :

Thanks for the patch, this is now fixed in the newly released udpcast 20230924.

This version also no longer uses 232.0.0.0/8 addresses as data multicast addresses by default (these are Source-specific multicast, which was actually not properly supported), and actually adds support for SSM. This might have been another stumbling block for non-local multicasts.
