Hi, everybody.

FreeSWITCH Version 1.2.6+git~20130104T154559Z~a4247651ca (git a424765 2013-01-04 15:45:59Z).

I have 2 interfaces in FreeSWITCH server:
-eth0 with public IP, where all gateways are located.
-eth1 with private IP, where all VoIP equipment (FXS, FXO GWs) are placed.

The source [http://wiki.freeswitch.org/wiki/Clarification:gateways] tells about 3 different ways of configuring gateway.
I use the 3rd one: freeswitch\conf\directory\default\<Gateway_name>.xml.
For examle look at the attachment.
I use it as all things corresponding with a gateway are at the same place:
- ACL (<user id="ThruToInfoIndust_192.168.15.60" cidr="192.168.15.60/32">)
- gateway (<param name="..." value="..."/>)
- user variables
(
    <variable name="toll_allow" value="domestic,local"/>
    <variable name="IsFromInfoIndust" value="true" direction="inbound"/>
)
P.S. This variant required only in
<param name="apply-inbound-acl" value="domains-<profile>:public"/>
 in all profiles, where
<list name="domains-<profile>" default="deny">
  <node type="allow" domain="$${domain}"/>
</list>
P.P.S. Variable "IsFromInfoIndust" used as because of "apply-inbound-acl""domains-<profile>:PUBLIC"
 . Where is a transfer to default context in case of this variable in public context.

But now several gateways are moved inside private network (with the help of VPN).
So I need to configure these gateways to corespond with internal profile (now all packets to these gateways, for example, OPTIONS, go thru internal interface but with external IP as source IP).
How can I do it for best?

With best regards,
