How to optimize ip nat rules

Hi, I'm preparing a CGNAT configuration like in the wiki article and I'm concerned about the speed of parsing ip nat rules. For example if I'm going to map ~250 private ip address and I'm reserving 512 ports for NAT per private IP, then I can put 126 private IPs per public IP, so I need 2 public IPs...

Re: PtMP maximum wireless performance

In fact is 40Mhz (20+20) Your screenshot shows layer1 modulation speed of 300 Mbps.. this is if you use 40 MHz channel wide, two polarization, so: 40V+40H.. Specs say : 4 connectors N per external antenna, so I'm pretty sure is not just one polarity. That's right: you have freedom to configure the ...

Re: PtMP maximum wireless performance

The problem is you are using a post-wifi system with all its flaws like -the system is not only driven by AP but by CPEs too. -the system doesn't know the "air" capacity so can't know the total bandwidth available -as the above is not clear, there is no way enforce any real QoS on the wireless links...

Re: CCR1036 memory upgrade question

Hi Normis

is there any chance Mikrotik can serious consider developing a video transcode app for the CCR ? If so, can you please provide any contact in your organization to discuss this ?

Re: CCR1036 memory upgrade question

Hi Normis why you at mikrotik doesn't develop a mikrotik package for video transcoding based on ffmpeg and the tilera medialib? (fully optimized for the tile platform)  You have other modules like hotspot, proxy, etc.. this can be a new application for this equipment... Even you can sell it apart!! ...

Re: Question about SFP+ 10G, 10km, 1310nm mikrotik module : are they 10GBASE-LR compatible?

Hi, thank you for the answer: may be the question should be: Is the mikrotik module compatible with 10BASEG-LR ? (this mean interoperable with other sfp+ 10g on 1310nm and able to distances up to 10km?) Other vendor SFP+ for that parameters (1310nm,10km) say 10BASEG-LR compliant but mikrotik doesn't...

I tried changing the interface queue type from "only hardware queue" to "default fifo" without success. Is this correct? Is there another way to do this?

The CCR 1009 is running latest stable (bug fix version 6.32.4) and it is just routing between two subnets. It is used for feeding an IPTV headend and it is moving > 300 Mbps and...

Re: Two RB493G, different S/N but same MAC address???!?!?

Hi,

yes I have changed the MACs on one of the routers to bypass the issue.

Both routers have the same factory default MACs , the serial numbers are different.
