Hi all,

Here is my setup :
                        ------------------------------            
local sipphone ------> |lan1 (router running FS)  wan1|--->internet
                        ------------------------------            

local_ip_v4 is set to lan1 address

wan1 has a dynamic IP address.
On startup, when wan1 has an IP address, I add the entry in my /etc/host : xxx.xxx.xxx.xxx my_host

I would like to tell FS that the external profile has to be created on wan1 with :
<param name="rtp-ip" value="my_host"/>

It seems good, the external profile is created. But the registration of my SIP account failed.

The working conf for registration is to set rtp-ip and sip-ip to local_ip_v4, and to have ext-rtp-ip=$${external_rtp_ip} and sip-rtp-ip=$${external_sip_ip}
But in that case, it can't route outgoing calls (see attached file).

I don't konw how to fix it.

Thanks for your help.
