Technically DNAT is correct. REDIRECT is just a shortcut to change the destination IP address to the local machine and leave the destination port unchanged.

> If I define a rule for NTP, I get two log entries ( one with 'DNAT', one with 'INPUTFW' ). A similiar rule for DNS produces one log message only.

Any NAT rule with logging enabled should always produce two log entries. One for the ‘nat’ table and another time when it hits the ’filter’ table.

Hi Daniel,

I tried to eliminate this double messages.
First I found the standard rules in 'Incoming Firewall Access' for DNS 
enabled. Interpreting these as the 'RETURN' rules discussed in the 
development process, I defined similiar rules for NTP.
The 'INPUTFW' messages are gone. They show up again, when I enable 
logging for these rules.
Maybe this helps a bit to clarify the issue.

I have checked my logs and cannot confirm this.

15:16:30 	INPUTFW 	blue0 	UDP 	192.168.56.127
192.168.56.1 	57803
53(DOMAIN) 		b8:85:84:a6:a0:f7
15:16:30 	DNAT 	blue0 	UDP 	192.168.56.127
192.168.56.1 	57803
53(DOMAIN) 		b8:85:84:a6:a0:f7
15:16:30 	INPUTFW 	green0 	UDP 	192.168.55.30
192.168.55.1 	123(NTP)
123(NTP) 		00:1a:e8:ad:07:52

192.168.55.1 	123(NTP)

As you can see, two entries are always generated for me.

Label 'DNAT' in the logging isn't nice. 'REDIRECT' would be more helpful.
If I define a rule for NTP, I get two log entries ( one with 'DNAT', one 
with 'INPUTFW' ). A similiar rule for DNS produces one log message only.

Re: IPFire 2.27 - Core Update 160 released

[Daniel Weismüller]

[-- Attachment #1: Type: text/plain, Size: 2236 bytes --]

Hello
I have also had a look at this. 
There are now two Wiki pages on this topic. 
- A general one (https://wiki.ipfire.org/configuration/firewall/rules/redirect-services).
- A very specific one for DNS redirect (https://wiki.ipfire.org/configuration/firewall/dns).

Since core160 the general method works. This is equivalent to the method 1 described on the specific page. 

Following the general instructions, I have created a few firewall rules to redirect DNS, DoT and NTP.
This works very well now. 

In general, I think that general instructions are always better than specific step-by-step instructions. 

In my eyes, the described method 2, which had to be taken as a temporary solution, is therefore obsolete. In addition, pure blocking can lead to some devices no longer working.
 
Do you see it the same way?

Hi all,

Thanks.
So it was only a misunderstanding. I thought, there would be options to 
redirect DNS requests and NTP requests.
But this 'any port solution' is much mightier.
I'll try to convert my actual firewall.local solution to the main stream 
and report about the results.

Regards,
Bernhard

Hello,

Simply using -j REDIRECT.

This was always part of the firewall engine, but the UI was broken and did not allow to create these rules.

Just a question. How is the activation of redirection implemented?
