[freenet-support] Port restricted cone NAT detected -- 60 times

[Joel Salomon]

My node has given me 60 copies of the warning:  Port restricted cone
NAT detected
Your internet connection appears to be behind a port-restricted NAT
(router). You will be able to connect to most other users, but not
those behind symmetric NATs.

Is there a way to clear all warnings at once, and is there a port I
can set to forward on my router to make this go away?
