PAP2T can't connect to login server after internet connection dropout
I have a Linksys PAP2T connected behind a Netgear MBRN3000 UMTS Router. Everything is working so far.
Some hard facts:
Sometimes my internet connection is dropped (weak signal might be the main reason) but the router reconnects very quickly (<1 minute). After every reconnect it get's a different public IP address assigned by my ISP.
After each of this reconnects, my PAP2 is just telling me "can't connect to login server" as registration state...
I tried putting the PAP2 into DMZ and changed some other stuff on the Router (something about SIP ALG) but nothing helped.
Since Netgear as well as SIP-provider's guy's don't seem to be qualified to even understand my problem, I'm trying my luck here
Anyone got an Idea what might be the problem and how to resolve it?
