Re: New Packet flow diagram

I propose to consider another option
Great work there!

I like as well - but, is there any way to make it horizontal instad of vertical?
If it was horizontal, it would fit on a widescreen monitor much better.

Also, there is bunch of spelling errors, and on the right side, it should say Encapsulation (currently says Decapsulation).

But great work otherwise!

Could you please please please upload an editable version?

Some changes, for a better understanding of travel of packets.
Fixes:
2014.04.05
- Corrected position 'IPSec Decryption' and 'IPSec Encryption' boxes in ROUTING (gratitude: macgaiver);
- Fixed form blocks 'Bridge Decision' in 'Forward' and 'Output' Chain.
2014.04.10
- Added "Configurable Facilities": Menu items of RouterOS corresponding function blocks;
- Corrected name of block "Decapsulation 
(TE, VPLS, VLAN, Tunnel)" to "Encapsulation (TE, VPLS, VLAN, Tunnel)" in "OUT-INTERFACE 
LOGICAL" line;
- Corrected name of block "Bridge Adjustm." to "Routing Adjustm." in "Output" chain (gratitude: greek);
- Corrected bloks in "Input" and "Postrouting" chains: "Global HTB" > "HTB Global | Queue tree", added "Simple Queues" (gratitude: greek);

Nice one - very informative. Just "IPSec Decryption and Encryption boxes need to be swapped - traffic comes to router and in case it is IPSec it will have policy and will be decrypted, not encrypted
and when leaving if there is IPSec policy it will be encrypted - this fix was also done on the wiki:
http://wiki.mikrotik.com/wiki/File:Pack ... m_v6_b.svg
With great knowledge comes great responsibility, because of ability to recognize id... incompetent people much faster.

Why last block in output chain is "Bridge Adjustm"?
In original scheme it's "Routing Adj."

And why "Simple queues" blocks is absent in "Input" and "Postrouting" chains ?

This is fantastic. Thanks for the effort as I think this layout helps you connect the layers together better than the original separated diagrams. Hopefully it becomes the official one.

To me the first version of diagrams is easier to consume. Second version is a little bit noise. There is too many arrows. Main content is hidden in the web of transitions! Arrows that define logical layers is too big, it's not the main content.

You can download the source in Microsoft Visio 2010 and disable the extra layers, making it easier diagrams at its discretion.

Why first and last figures in output chain are not a parallelepiped as in original scheme?

As i know, parallelepiped has concretic mining in flowchart http://en.wikipedia.org/wiki/Flowchart

Nice comprehensive graphics!

May I suggest to stick with english grammar rules for questions: auxiliary verb, then subject, then verb

Decapsulation is needed? -> Is decapsulation needed?
Encapsulation is needed? -> Is encapsulation needed?
It's IP Traffic? -> Is it IP traffic? ("It is IP Traffic" is a statement, not a question)

These changes would give decisions a consistent wording.

Trying to implement your double qos suggestions for hotel. I want to proritize traffic in queue tree and limit per user with dynamic simple queues. I can generate the simple queues in dhcp lease but what happens if a customer sets his own static ip? How can I generate his queue so that he does not bypass the limits?

1) authorization
2) just create a queue for 'everyone else' (10.0.0.0/16) with hard limits :)

Re: New Packet flow diagram

Fri Mar 25, 2016 12:37 pm

I have a clarification question regarding the order of mangle and routing processing of the "output" chain.

I want a script on my router to connect to a fixed-ip website via a predefined WAN connection (in order to get my external ip on that connection).
The set-up is the following:
  1. mikrotik 951G-2HnD v6.34.3
  2. two WAN connections on ethernet ports: first is a default (higher priority in routing), second is a failover (lower priority in routing)
  3. my ip-firewall-mangle rules section contain a rule on "output" chain to mark a non-marked connection to a fixed-ip destination
  4. my ip-firewall-mangle also contain a rule to place a routing mark on all marked connections to a failover WAN (via routing table)
All is working perfectly as planned.

However, according to http://wiki.mikrotik.com/wiki/Manual:Packet_Flow_v6 the output chain does not go through a "routing decision" block (K->L flow). The absolutely fantastic new diagram in this thread also shows that local "output" block with "mangle-output" is located after the "routing decision" block (also K->L flow).

My setup clearly shows that mange-output is before "routing decision" block since routing mark changes the flow to a failover WAN connection (non-default in routing table). Without my mange rules connection goes to a default WAN connection.

And my questions are:
  1. Is it really correct on the diagrams that "output" block from local output is placed after a "routing decision" block in the flow?
  2. Is there a single-mangle-rule solution to mark all traffic (local and forwarded) going to a fixed-ip with a connection/routing mark? [I now have two identical mange rules: one for "output" and one for "prerouting"]
EDIT: is it a "routing adjustment" that actually works in my set-up? Is it not better simply to have a "routing decision" after the "output" block? Why this design decision was made?

I have service at 192.168.0.2:12345

I added the rule:
ip firewall nat add chain=forward action=dst-nat protocol=udp port=12345 to-addresses=192.168.0.2 in-interface=ether1 log=yes
but the log remains empty

Dst-NAT rule doesn't work when it isn't allow rule in input chain of filter:
ip firewall filter add action=accept chain=input in-interface=ether1 protocol=udp port=12345 place-before=3
According to the diagram packet in general can not get into the INPUT.

Hello,

@busla:
this thread about the new packet flow diagram was started 3,5 years ago and packet flow management is a central feature of routers in general

Do you really think, your problem now relates to this packet flow diagram itself ?
Please try to understand the packet flow diagram by reading appropriate information - either here in the wiki or by searching Google.

Your problem is knowledge- and config-related.
I second nest (Ron) => open up a new forum thread, thank you

The diagram is a part of wiki. I have studied it.
My sample is a sample, not a problem. I want to know a real 'paclet flow' in RouterOS. It solve all my problems.

Hello guys !
I'm looking at those packet flow diagrams and the exemple scenario and I was wondering : where does the traffic originating from the router itself appears ?

For example let's say I bind a dhcp-client to a vlan interface, what would be the path of a DHCP Request packet on those diagram ?

Router originated packets are always output->postrouting.
Look at, where input are packets targeted exclusively to router (or not-NATted for example), and output are exclusively outgoing originated from router.
