I have a port lease which would have last been used on Aug 25 or earlier when I changed the host's IP address but it still shows and I assume is stopping the new IP address from making the same port forwarding rule. How or when does miniupnpd expire leases?

For the moment I've had to manually remove the lease from /var/lib/miniupnpd/upnp.leases

port Leases have a duration, that could be infinite, so it will never expire.

you should not manually remove leases, just use a UPnP IGD client to do that.

I am afraid I don't fully understand the process. What sort of client are you talking about? Does it run on the same machine as miniupnpd or elsewhere?

Usually elsewhere. MiniUPnPd is an UPnP Internet Gateway Device (aka IGD) implementation. In UPnP terminology, clients are called "control points" and are piece of software on other LAN hosts.
What are the control points you are using ?

Thanks for the explanation. In this case the control point is a ClearOS7 server running in a VM. I am playing around with it as a Sia host and I assume the Sia daemon has the UPnP IGD client in it.

If available, you can install miniupnpc on the ClearOS machine and use the upnpc command line tool

I'm bumping this old topic as I still don't fully understand.

My set up is ClearOS7 gateway running miniupnpd and on the network behind it are various devices such as a PS4 and another bunch of ClearOS7 servers, one of which runs Sia (which uses uPnP).

If the PS4 is turned off, what causes its leases with miniupnpd to expire? Ditto the ClearOS servers running Sia?

Please use miniupnpc (or another client) on any host on your network to display which leases are active.
Code:

$ upnpc -l
upnpc : miniupnpc library test client, version 2.2.0.

I've tried miniupnpc 2.2.2 but it won't run:
Code:
[root@microserver miniupnpc-2.2.2]# upnpc -l
upnpc: error while loading shared libraries: libminiupnpc.so.17: cannot open shared object file: No such file or directory
But:
Code:
[root@microserver miniupnpc-2.2.2]# updatedb && locate libminiupnpc
/usr/lib/libminiupnpc.a
/usr/lib/libminiupnpc.so
/usr/lib/libminiupnpc.so.17
/usr/src/miniupnpc-2.2.2/libminiupnpc.a
/usr/src/miniupnpc-2.2.2/libminiupnpc.so


So I have tried the old precompiled Windows client:
Code:
C:\Users\Nick\Downloads\upnpc-exe-win32-20150918>upnpc-shared.exe -l
upnpc : miniupnpc library test client, version 1.9.

My underlying issue, which this demonstrates, is that the lease time is blank and the lease never expires.

On the gateway I am running miniupnpd-2.1-12.

use
Code:
upnpc -d
to remove a lease.

Leases without expiry time... do not expire.

Who sets the lease time? The client or miniupnpd server? In the DHCP model it is the server that sets the lease time. How does it work in UPNP?

The client sets the lease duration.

So this would be a bug in the PS4 software?

what bug ?
I guess the software doesn't set a limited duration time because it is meant that way
