Hello,

I have some problems running a FreeSWITCH with endpoints located in different subnets. For example a FS is listening at 192.168.50.14/32 and endpoints from the same (192.168.50.0/24) subnet work as expected. But when I try to receive a media from an endpoint located at different subnet, let’s say 192.168.60.0/24 the RTP stream cannot be bridged. FS sends an INVITE message asking endpoint to send media to external interface.

Can anyone give me a hint where to look on how to overcome such behavior?

Kind Regards,
Andrey Nepomnyaschih

Maybe your router isn't really a router and is doing NAT behind NAT? Need logs and sip traces because we would only be guessing at this point./b

Hello Brian,

I don’t think there is NAT relation between these two subnets (192.168.50/24 and 192.168.60/24) because hosts that reside inside 192.168.60/24 are accessible from 192.168.50/24. I’ve attached a sofia_trace.zip file with output with sofia loglevel all 9 enabled.

Hello Frank,

There is only one interface on FS box, it has an IP address 192.168.50.14/24 and the 192.168.60/24 is accessible through 192.168.50.3. Correct me if I'm wrong, but if I set the mask to be /16, then 192.168.60/24 will be unreachable from FS as it will be treated at local connected network.

Yeah, I've been working with Network Admin on this issue, and he says that the router simply routes the packets without doing any translation stuff. Although he couldn't answer where exactly the RTP stream is going to, so we agreed to switch from one software to another tomorrow and see if makes any difference.

Its because your local-network-acl doesn't include that other network
please correct that and it'll work.

No luck.

These networks (192.168.50/24 and 192.168.60/24) are now connected through another transit network (10.15.118.252/30) without using any firewall or tunneling software. But FS still asks that endpoint to send RTP media to external IP address and I'm really lost with this problem.

Thanks.

That did the trick and now FS sends the correct address.
