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:

  • PAP2T
  • Software 5.1.6(LS)
  • Hardware 0.1.5
  • IP: static

The Issue:

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?

Thanks in advance,
