Two L2TP connections through the same NAT firewall

Senario:
ASG 6.303 with L2TP configured for client connections.

Two clients behind the same NAT firewall can't connect to the ASG at the same time. The first client (either one) connects to the ASG just fine. But the second client just times out. I've tried a few NAT firewalls at the "client side" with the same result. So I'm pretty sure the issue is on the ASG side.

NAT-Traversal is enabled on the ASG.

Is this working as designed or can this be a bug or a faulty configuration?

Thanks,
/Hansi

I think this is a limitation of the L2TP - have you tried with PSK or Certs?
