By "the API" I presume you mean "the sockets API"?  I misunderstood you
when you said you were using lwIP directly without any of the APIs, but
as you're using the raw API that's OK: my apologies.  Having read
rawapi.txt I can see where this confusion arises from!

To do the things you require should be reasonably straightforward with
the raw API - it's all callback based, and you can distinguish
connections using their pcbs.

Can you explain what you need to do to iterate through the connections? 
This might help come up with a good way to do this.  In normal usage you
would set up callbacks so that you are prompted to do any required
actions, and connection iteration (to, for example, see if there are any
data to read) would not be necessary.
