Adding mapping with lifetime 0

[DigDugFTW]

Adding a mapping with lifetime 0 works once mapped, but when the mapping collection is enumerated it throws an "ArgumentOutOfRangeException" stating that lifetime was out of range of valid values.

I created a mapping a couple of hours ago, the mapping doesn't last infinitely and can be over written.

I only created a mapping with lifetime 0 because intellisense stated that for the lifetime parameter setting it to 0 would be permanent or infinite.

I created a mapping a couple of hours ago, (1) the mapping doesn't last infinitely and (2) can be over written.

(1) Open.Nat doesn't control what your router does, your router's software does it. The library simple performs a request to your router's http server for opening a port, how it handles the request and what it does after that is out of the library control and is different from router to router. The spec says that a lifetime=0 should keep the port opened.

(2) Yes, it can be over written, otherwise client software would never extend the expiration date or remove mappings once they are not needed any more.

Ummm... this looks like a defect. Could you share the log file please? In case you don't know how enable the tracing, take a look at this config file: https://github.com/lontivero/Open.NAT/blob/master/Open.Nat.ConsoleTest/app.config
