I guess that you just need to add a rule to your simple router's config
that permits udp 4569 from asterisk outbound to any IP address.

Subject: [asterisk-users] IAX2 NAT issues
Hello,
I am playing around with IAX2 and I have encountered a problem trying to
setup an asterisk box through NAT using IAX2.
This is the problem:
Asterisk box => Advanced Firewall => Internet => User's router
=> User
The user can register, the server can answer, calls can be made.
Asterisk box => Very simple router => Internet => User's router
=> User
User's packet reach the server, the server cannot reply because the udp
connection is lost, several RX retry TX retry, user is unable to call.
In both cases the firewall and the router are forwarding the port 4569
to Asterisk, user's router is not forwarding anything, the user has
qualify=yes to maintain the connection open but the very simple router
will drop the connection before Asterisk can reply to the packet.
So I ask the list: Is there a way to overcome this problem? Udp
connection timeout in Asterisk? Should I get a new router?
Thanks,
PLL.
