Error messages
Source and destination IP addresses are from the same subnet.

Hey Jon,
You probably want “any” as destination.

Hi Stefan,
Thank you for taking this on!
I applied the patchwork.ipfire patch.
I think I entered something wrong since I cannot get things to work. I tried both with Destination Firewall GREEN & Firewall RED.
Does the Firewall Rule seem right?
Best regards,
Jon
Here is the rule I set up:

Hello Matthias, Hello Michael, Hello Jon, Hello *,
I've followed the conversation on this list since the first mail and
thoughts about forcing DNS traffic to use the local resolver.
It was a very long journey and lot of time and work has been spent to
get to the present point.
As Michael requested here, I've digged through the lines of the perl
script which is responsible for creating the firewall rules and
surprisingly found that everyting which is needed to create generic
REDIRECT rules already was written in the past - it just did not work
as designed/expected.
Finaly I was able to adjust these lines of code and to repair that
feature.
A redirect rule can be created by picking a single host or group of
hosts or entire network(s) as source, selecting NAT (DNAT) and choosing
the Firewall itself as target.
The protocol or service or service group which should be redirected has
to be selected afterwards. If you want to redirect a given port to
another one it can be specified as "Target port".
All created redirect rules are displayed as "input rules".
The patch directly can be accessed here:

Hi Michael! Happy Monday!
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?
Doing a DNS redirect, via the WegBUI, has been an issue since
2015. I found this quote in the old forum:
"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."
And these cannot be changed?
And I found this from 2016:
https://bugzilla.ipfire.org/show_bug.cgi?id=11168
So I am guessing that no one has been able to determine a way to
extend the WebGUI.
Has anyone tried? I do not see any obvious reasons why this should
not be possible.
I am curious - Who created the
https://ipfire:444/cgi-bin/firewall.cgi page? And could they help?

From: Marcel Lorenz <marcel.lorenz@ipfire.org>
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?
