Im trying to use openser as a Proxy for different interfaces in one box I have
tried almos averithing to
make it work properly but for some reason I cant.
Here is my setup and I hope
someone can helpme or guide me in
the right way.
One Linux-OpenSer
box with 4 netcards
1 Has a public ip
2 Has a 192.168.23.10 ip
3 Has a 10.254.10.240 ip
4 Is not being used
I want to be able to make
calls from the ATAs in all the different networks,
but the fact is that as it is now I cant, I want to know if I have to set up
multiple media proxies or rtpproxy if I have to use a
proxy dispatcher or not.
This is my configuration file

As you can see I use different
starting numbers for the ATA for each of the interfaces, I tested using only
one mediaproxy listening to 127.0.0.1 but I have
tried a lot of configurations, all the clients register perfectly but cant seem to call one another exept
the ones that are on the same interface.
Im using fedora core 3 with openser 0.95 mediaproxy 1.42
Hope any one can help me or
point me the way to do this of if its not viable or
cant be done.
Thanks a lot for your kind
help
Yours truly
