 |
|
Hi
upnpc works great for me, thanks.
However, there seems to be some security built in that I don't understand how to modify.
upnpc -r 80 TCP
fails with code 718 ConflictInMappingEntry
I realize this is a security measure, how do I bypass this though?
thanks |

it depends on your router and its configuration.
Traditionnaly ports blow 1024 are considered as "system reserved" or "privilegied ports". Only ports above 1024 are "unprivilegied" and open to all users/applications.
That is why P2P applications usually use ports > 1024.
Anyway port 80 is probably already in use on your router.
But in anycase, most router wont (or should not) allow to mapping on ports < 1024 through NAT-PMP or UPnP.
Use the configuration interface if your really know what you are doing.
