Bekijk de volledige versie : WL500gx: VoIP with DHCP works, static IP not

Dear Forum members,

I have set up my WL-500g deluxe with a Sipura SPA 2000 voice over IP adapter attached on a LAN port, which has two phone lines configured with two providers (sipgate.de, dus.net). If I configure the SPA to use DHCP to get its IP address, everything works fine (using STUN, no port-forwarding). If I configure the sipura to a static IP address (successfully, as I can reach the administration interface using this IP), both SIP accounts cannot register to the provider. Pretty much default setup otherwise. Firmware is stock Asus 1.8.2.1. Why does this make a difference? Any ideas or known bugs in the Asus firmware? If so, is this fixed in Olegs firmwares?
Next, I will play around with port-forwarding etc, but I still do not see why the one setup works and the other doesn't...
(I definitely want to move to static IPs for my own equipment, and limit ports/services for DHCP clients, to be able to leave my network open).

thanks a lot in advance,
TSCoreNinja

Have you tried to use dhcp but assign the sippura a static ip based on mac-address? In other words sippura is set up to use dhcp, but it gets the same ip from wl500g everytime. Or is that whats not working?

Not yet, good point, will try that out tonight and report what happens.
However, I am really puzzled by the difference, because I do not see how the negotiation of the IP should affect the operation once the router and ATA have agreed upon an IP. The longer I think about it, the less it seems to make sense. Or am I missing something?
Thanks for the answer,

Sorry to have bothered you, problem is solved. I overlooked that if I assign IPs manually, the DNS server will also not be assigned automatically. I guess it helps to enter the DNS server manuallly then... Brown paperbag over my head...
