Sven Auhagen 74dbad5ab0 IPv6 pinholes lease file 
This patch adds a lease file for IPv6 pinholes.
The leases are maintained and readded when miniupnpd restarts.
Currently all IPv6 leases are lost on restart.

Pali Rohár 7ee554d31b miniupnpd: Disable port forwarding when upstream interface is down 
Obviously port forwarding cannot work when upstream interface is down. So
correctly report status code for port forwarding requests to clients in
this case.

Natanael Copa 1aa46b5a2c miniupnpd: improve error message for bad config 
Improve error message so users don't need read the source to figure out
why miniupnpd refuses to start even if the usage is correct.

Thomas Bernard 207d1849e4 miniupnpd.c: typo and ip -> IP 2021-01-15 19:33:29 +01:00
Pali Rohár e6bf74a691 Add check that miniupnpd is not going to listen on WAN interface with public IP address 
Option listen= is used for LAN interface/address and option ext_addr= is
used for public IP address. If users by mistake swap WAN and LAN interface
or public and private IP addresses then miniupnpd obviously would not work
and instead of hacking miniupnpd code users should rather check their
miniupnpd configuration or local firewall settings.

So add checks and hints which prevents security issues like swapping LAN
and WAN interfaces/addresses and therefore prevent exposing port forwarding
and firewall configuration on public Internet.

Pali Rohár 8e10a1aeab miniupnpd: Disable port forwarding when we are behind restrictive nat with reserved / private IP address
