Script to Clear Ports Forwarded By UPnP

[tbrock47]

I'm looking for a command/script that will essentially clear any ports forwarded by UPnP (not necessarily all ports if possible) as I find many ports are not auto-closing.
My current solutions are rebooting the router or disabling and then enabling UPnP via the GUI, both of which are not ideal.
I'd like to be able to either run it on-demand via SSH or set it up to run on a schedule (cron?).

Thanks in advance!

Try:

iptables -t nat -F VUPNP
iptables -t nat -F PUPNP
iptables -F FUPNP

Try:

iptables -t nat -F VUPNP
iptables -t nat -F PUPNP
iptables -F FUPNP

One or more of those seemed to do it. However, there was no "PUPNP" chain in the nat table.
Do I actually need all three commands?

admin@RT-AC5300:/tmp/home/root#
admin@RT-AC5300:/tmp/home/root# iptables -t nat -F VUPNP
admin@RT-AC5300:/tmp/home/root# iptables -t nat -F PUPNP
iptables: No chain/target/match by that name.
admin@RT-AC5300:/tmp/home/root# iptables -F FUPNP
admin@RT-AC5300:/tmp/home/root#

Whether the PUPNP chain exists or not depends on which firmware you're running. It's best to issue all 3 commands anyway (just ignore the errors) so that everything is consistent.

Perfect. Thanks so much!
