I used a similar rule, but faced with the problem that is described in a new topic - UPnP incorrect a response port. (ROS v6.31)

I has set strong firewall filtering rules and encountered a problem in UPnP - response packet from MikroTik does not match the destination port specified in the original request. An example of a captured packet: Request: IPv4: Src: 192.168.88.2, Dst: 239.255.255.250 UDP: Src Port: 61042 (61042), Dst...

You can give only one mangle exemple for the two tables (double WAN with QOS HTB) in version 6.7 ? Interface Ether 1 = WAN-A ( IP-1 10.10.10.10 ) <-Default Route. Interface Ether 2 = WAN-B ( IP-2 20.20.20.20 ) <-Second Link (With LOAD BALANCE WEB CONN PORT 80) Interface Ether 3, 4 , 5 = (LAN Bridge...

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 an...

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 ?

Fixed - see updated my post
Thank you!

Nice one - very informative. Just "IPSec Decryption and Encryption boxes need to be swapped

Thank you, fixed - see updated my post.

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 Facil...

Nice... PDF or SVG or some sort of vector image would be ideal. Looks great though.

See my previous post.

Fixed small bug

I propose to consider another option
