Why do we not extend the firewall UI probably by about 20 lines of code instead of adding many hundreds of lines?
Please can someone elaborate on this more?
"Having investigated a bit more I have concluded that it's not currently possible to create such rules through the WUI.There are a number of obstacles:1. It is not allowed to create a rule where source IP and destination nat IP is on the same subnetwork (e.g. GREEN), WUI error message: "Source and destination IP addresses are from the same subnet."
2. WUI will not allow you to create a rule without a destination (the filtered packet must adhere to a destination, not only a port) and the destination MUST be an IP address of one of the IPFire interfaces, which limits whats possible a great deal."

Thank you for sending this patch on Marcel’s behalf, but I would much more prefer if he would submit his patches on his own. I do not see why that isn’t possible.Please note:
This is a new addon written by Marcel Lorenz <marcel.lorenz@ipfire.org>.
It adds a new GUI to IPFire for DNS/NTP *and* user specific port redirections.
How its working:
It has exactly the same functionalities as "Forcing DNS/NTP..." - and some more.
By setting switches, DNS/NTP requests are automatically
redirected to the local IPFire DNS/NTP servers.
Additionally, the user can specify custom redirections.
These rules are added to a new chain in PREROUTING => PORT_REDIRECT.
To avoid problems with (e.g.) transparent 'squid' configurations,
redirection rules are added automatically before existing 'squid' rules.
This message does unfortunately not say why this add-on would be useful. I am emphasising this again and again that it is not very important how something is done specially. That should be commented in the code and other implementation details should also be documented there.
As I have stated on this functionality many times before, I do not see why this is necessary at all.
Why is this an add-on?
Why do we not extend the firewall UI probably by about 20 lines of code instead of adding many hundreds of lines?
Please can someone elaborate on this more?
