Hello, I have a sip client (Android Csipsimple) connected to my FS server. Any outbound calls i make drop after some time. The FS server is running in a FreeBSD jail on a separate network (192.168.10.10) to the Android phone which is on a LAN (172.16.1.21). I have the following acl defined. <list name="natme" default="allow"> <node type="deny" cidr="192.168.10.0/24"/> <node type="deny" cidr="172.16.1.0/24"/> </list> <list name="nonat" default="deny"> <node type="allow" cidr="192.168.10.0/24"/> <node type="allow" cidr="172.16.1.0/24"/> </list> In internal profile (internal.xml) the acl is setup as <param name="apply-nat-acl" value="natme"/> <param name="local-network-acl" value="nonat"/> Following is the wire-shark representation of the call. Any idea what my call is being dropped?
