I'll go with B. The inability to inspect the encrypted signaling messages is a pretty big deal when it comes to implementing NAT ALG for real-time communication.

Hmm, I'm not sure about this one. If the signaling messages are encrypted, how is the NAT ALG supposed to work? B sounds like the right answer to me.

I think the answer is D. Source addresses cannot provide the destination addresses that remote endpoints should use for return packets, which seems like a significant issue with NAT ALG.
