Speak freely from behind a router

Speak freely from behind a router

[Henning Oschwald]

hi,

can somebody tell me how two computers behind a router can connect a
speak-frely-reflector at the same time? The problem is, that sfreflect
works on port 4074 by default. The router must forward this port to a
computer in the lan. But one port can only forwarded to one client at the
same time. So both clients behind the router can send voice data to the
reflector, but only one client can receive data.

Can anyone please give me a solution for this problem?

best regards,
Henning

actually, thi is not a blinux-related topic but okay here goes:
btw, no waranty whatsover on the success of this.
Now you have to see the sfreflector manpages for this or use the 2nd but
rather hacky method I'm gong to suggest to you.
1. setup a local reflector and make sure it has 2 monitoring-varibbles, the
first is going to point to the host the actual reflector runs on, the 2nd
to a sfspeaker copy on your local machine.
Now you can use sfmike to send to your local reflector and on the 2nd box
you just can contact to your local reflector as you would normally.
If I'm correct, you will send audio-data to the local reflector which will
be send (via the monitor) to the remote reflect which actually will see
this as a connection and therefore send data back to you as well (but not
the data coming from you.
Now this might give some troubles with audio-data from your local partner
or so.
2. okay, use one sfspeaker unit with the -R flag and give up a filename,
create a named-pipe bij using mkfifo with the name of the file you give on
the sfspeaker commandline.
Now use a second copy of sfmike to read from the named-pipe and transmit it
locally to the second machine wheile the first machine actually transfers
it's sound directly to the reflector on the remote site.
As the reflector sees you both as the same connection, locally generated
conversation will not endup with the other local-user at all.

Good luck and let me know if anything of this helps as all.
