Appreciate that, You used stun protocol to detect external IP address although I'm using the exact address so I think it makes no difference. I would appreciate if I know in which conditions FreeSWITCH uses public IP address in SDP protocol. On Saturday, August 16, 2014, Douglas Adami <webmaster.rumodigital@gmail.com> wrote:
Hi Afshin,
I have the same scenario as you and 100% functional, this is my setup.
<X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org"/>
<param name="apply-nat-acl" value="nat.auto"/>
<param name="rtp-ip" value="$${local_ip_v4}"/> <param name="sip-ip" value="$${local_ip_v4}"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/>
I'm new around here, so let's wait for a response from some expert.
good settings

Hi Douglas,
Thanks for your reply, I)
In my scenario both of FreeSWITCH and client are behind the firewall.
II)
<X-PRE-PROCESS cmd="set" data="bind_server_ip=auto"/> <X-PRE-PROCESS cmd="set" data="external_rtp_ip=X.Y.Z.W"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=X.Y.Z.W"/>
I have a static public IP (for Freeswitch) and I know what it is so I specified it explicitly.
Do I have to set bind_server_ip to a specific IP in case of NAT traversal as I specified local IP addresses for sip and rtp?
III) in the SIP profile <param name="sip-ip" value="192.168.10.59"/> <param name="rtp-ip" value="192.168.10.59"/> <param name="ext-sip-ip" value="X.Y.Z.W"/> <param name="ext-rtp-ip" value="X.Y.Z.W"/> for apply-nat-acl I examined nat.auto, rfc1918, ... :(
I did not refer to external_sip_ip / external_rtp_ip vaiables in the SIP profile and explicitly defined external static IP.
BEST,
Afshin

Hi,
NAT scenario, correct? https://confluence.freeswitch.org/display/FREESWITCH/NAT+Traversal
try this:
vars.xml <X-PRE-PROCESS cmd="set" data="bind_server_ip=my.domain.com"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org "/> <X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org "/>
sip_profiles:
sipinterface_1.xml <param name="apply-nat-acl" value="nat.auto"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>

Hi Miguel,
I do not understand how the ACL (if you mean apply-nat-acl) can effects on using public IP in SDP when I specified both ext-sip-ip and ext-rtp-ip in sip profile! I changed the apply-nat-acl to a "always allow" and "rfc1918" but does not make difference.

Hi FreeSWITCHers:
I configured a sip profile as bellow:

for every INVITE that comes in via this profile, FS replys with this SDP:

Although the Contact header of 200 OK is correct : Contact: <sip:4000@X.Y.Z.W:5060;transport=udp>
