Hi Tom,
i am looking for a way to setup at child gk as a proxy which is forwarding all the registration requests to the parent gk. just a short description to my problem.
i setup a child gk behind a NAT as a proxy for the internal phones. i register as a gateway to the parent gk and setup at the .ini file the prefix which should be forwarded to my proxy child gk.
1.) at the moment every client is allowed to register at the proxy (not a good solution if the proxy is in a dmz)
It should not be hard to set up iptables (or a hardware firewall) to allow registration and Setup only from internal addresses and from the parent gk.
2.) with the prefix option i can tell the parent gk to forward e.g. 4711 to my child gk
question to 1.) is it possible to prevent clients to register at the child gk and only use the parent gk for registration?
I don't think so (but I don't know much about this area). However, if you just want central administration of your authentication, etc., you can have the child gk access the same radius, sql, etc. database as the parent.
question to 2.) is is possible to prevent the child gk to do any rerouting with the prefix option?
I don't understand your question. Do you have administrative control of the child gk? Where would your problem calls come from (local IP phones, parent gk, other source) and where don't you want them to go?
p.s. i am using 2.0.9 at the moment because the 2.2.0 died after every reset (24h) of my adsl line.
Oh, how awful. If "unbundled" DSL is available in your area, and there is a reliable alternate ISP, IMHO you should switch. In addition to solving the disconnect problem, you will probably get much higher upload speed, which you'll need if you want to handle several calls at once.
If you are stuck with the disconnect, is your IP address changed each time? If so, even if you can avoid gk crashes, all calls will drop, and you won't be able to reconnect them until the child gk has reregistered with the new IP. You may be able to avoid this by getting a static IP from your present ISP, or going to a new ISP, even if they must connect via your LEC's DSLAM and BAS that forces the disconnect.
If you are disconnected every 24h but keep the same IP, then with the proper modem/router you should be "down" for only about five seconds, and the gk shouldn't even notice. Unfortunately, calls in progress may drop, not because of a technical problem, but because five seconds of silence is enough to convince most callers that the line has gone dead, and they hang up.
Regards,
Stewart
