One more thing to add here, even though 2048 port limit looks too much but
this include TCP + UDP + ICMP flows, It doesn't differentiate. Secondly you
can't find out if it is handful of subscribers causing the port exhaustion
on their limits and resulting packet drops or this is happening across the
board. Probably put a host and try simulating it on your own.

CGN is always tricky to tweak. I'm using A10 now and sometime face similar
kind of issues..
