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.

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. _______________________________________________ Sign up now for AstriCon 2007!
