Hi,
sorry may be I missed something, but I could not find in the WUI the NAT-Reflection option.
If it is not available, the problem above is not as simple as you think it is.
I would be pleased if you could direct me to the right menu in the WUI.
Of course simple Port forwarding is supported by IPFire, which Firewall can’t do it?
NAT Reflection however is not supportet out of the box as discussed here, here, here, here and in other similar threads.
For a better understanding of the problem here is a very good explanation in Stackexchange:
Link.
Anyway, for future reference I got a solution for it:
In addition to the “iptables vodoo” above I added an additional Forward Rule: As source all other local IP’s except the server IP, selected SNAT with the external Red0 interface and as destination the local server IP.
This way I can configure all Apps using the DDNS Address, the connections will work inside and outside the LAN.
Greets,
Tobias
