 <u></u><u></u></p><p>We&#39;ve got an openwrt router at a site, it&#39;s private IP is 10.0.0.1. Whenever we get an inbound call on the external profile (and probably outbound calls to, haven&#39;t checked yet), it changes the contact IP to the router&#39;s private IP, so that every call we get looks like it&#39;s coming from thr router. We&#39;ve had some intermittent audio problems recently and we&#39;re trying to narrow things down a bit. Is this the expected behavior for NAT? <u></u><u></u></p>
<p>Sorry might seem like a dumb question, but my job entails much more than keeping the company&#39;s server&#39;s happy and I&#39;m starting to lose my grip and I&#39;m definitely not experienced with NAT.<u></u><u></u></p>
<p>All of my routers in the past have given FS the public IP of the contacting server. I have web servers behind the same NAT and doing the same thing, showing the private IP of the router instead of showing the public IP of the client. So I know it&#39;s not an issue with FS. Just wanted to see if anyone has exoerienced this before. Makes it difficult to use fail2ban on my servers, as it continually jails my router.<u></u><u></u></p>
