QUESTION The woes of double NAT issues

[kcallis]

I know once upon a time I knew this answer, but has escaped me. I just made the jump in playing with a Raspberry Pi, and as usually the install was flawless. My issue right now is that I am having NAT issues and can't seem to resolve it.

My Pi is connected to a Linksys 4200 router running DD-WRT. The subnet for that network is 192.168.10.0/24. The 4200 is connected to a Ubiquiti Bullet and the bullet is providing a WAN address of 192.168.20.200. The Bullet is connected wireless as STATION, an connected to the a Netgear 3800 router running DD-WRT as well. The network address is 192.168.20.0/24. From there is gets its address from DHCP.

I have setup the Netgear to allow for the Bullet to be seen as the DMZ. My thought was that I would be able to have all ports sent to the bullet and by default to my Linksys 4200. On the FreePBX side, I made the change to use an dynamic host name and pointed it to the Netgear router. After this and changing my softphone, I stated receiving calls, but still out going sound from the softphone.

What else do I need the change to make the two voice work?

Is there any reason you need to double nat? You could set your net gear to a 192.168.10.x address, shut off dhcp and plug everything into the LAN jacks and not use dhcp. I believe dd-wrt has an option to set it up as an access point instead of a router.

Finally figure out what the problem was... It would seem that my DD-WRT router was not updating the IP address correctly. Once that was fixed, things have been stellar, although I have been unsuccessful with getting PPTP working or being able to implement Travelin' Man...
