Hello all!
I’m having trouble following the changes to firewall.cgi.  I think
there were 4 or 5 patches 
submitted to the Dev Mailing List.
Did these get approved?
That is a good question. AFAIK they are not in c159.
...
I looked at the Changelog for Core 158 and core 159 (testing) but I
didn’t see anything:
https://nightly.ipfire.org/core158/2021-07-21%2015:47:35%20+0000-23498c61/x8...
https://nightly.ipfire.org/master/latest/x86_64/changelog.txt
Can they be added to CU 159?
To be honest I am mainly interested in the DNS redirect (and its
cousin NTP redirect).
I’d be happy to help test but I do need some help applying the
patches.  
Right now I apply them by grabbing a copy of firewall.cgi and
manually deleting and then manually adding a patch.
Not the smartest way but it works (if I don’t screw-up and make a
mistake!).
@Stefan: What is the status on this?
All firewall related patches, pending on the list, safely can be merged
and tested by a bigger group of testers.
These are the patches I found related to firewall.cgi.  I am not sure if 
these are all DNS/NTP redirect patches or if they are related to other firewall.cgi issues.

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:

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:

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."

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?
