I have a similar reading as well on my 850gx2... Free memory: 446.9 Total memory: 469.8 It would be nice to know if this was a normal thing. I was also expecting to see 512MB in "total" memory. A few years back, I owned an RB450G that actually had a total memory reading of MORE than was sp...

I have a similar issue. When it was just one xbox360 on the network, upnp always created open NAT. Now that there is a 360 and an XBone, they're both getting moderate nat. UpNp enabled still. Would love to get a proper solution to this.

SeaburyNorton

Does anyone know if it is possible to downgrade a recently purchased RB850GX2 to 5.26? I'd love to use this unit, but 6.X and winbox3beta are such buggy messes, I'd like to just use 5.26 on my setup. I'd just like to know if it is possible to downgrade or does the new unit have something in it that ...

SeaburyNorton

We will start shipping it on Monday.

Already ordered mine from you guys!

SeaburyNorton

I can confirm all is working again on 5.24

SeaburyNorton

I can confirm this issue on 5.24 as well.

SeaburyNorton

but who has them in stock?

Roc-Noc has a bunch. I just ordered a second one a few days ago.

There doesn't seem to be any in the American shops, either.

UPDATE: I've read that there was a production problem with the casing. We aren't going to see any more of these in the US until mid-to-late September.

SeaburyNorton

A new RB2011 died after upgrade from 5.23 to 5.24... wow I upgraded an RB2011 from 5.23 to 5.24 and then upgraded the firmware. Not only did it go smoothly, but a wireless ethernet bridge I had on the network is now able to connect without any dropouts (it was disconnecting every few mins on 5.23).

SeaburyNorton

I've been barking up this tree for years...

SeaburyNorton

I would like to buy one. Anyone have stock here in the US?

I purchased one from roc-noc.com. They have many in stock now...

In terms of wireless performance, if the router would be configured to run both G/N, is it possible for various devices to connect at different rates? For instance: 2 laptops only have wireless g, 3 other laptops have wireless N capabilities. Can all of these run at their respective speeds? G lapto...

I've run into a similar issue with cable modems... some companies tend to set them to "bind" to the first device they see... so, although you plugged in the mtik, the cable modem is still trying to find the mac address of the linksys box. Try pulling the power on the cable modem for a few ...

Couldn't you just specify those "manually"? Like: /ip dhcp-server network add address=192.168.0.100/32 dns-server=dns-for-this-IP What the script does is create static entries in dns for all dhcp leases to that they may be resolved by name easily. For instance, if dhcp1 is giving out leas...

I would also love to know the answer to this one... I'm running two dhcp servers on 2 different interfaces with 2 different network tags... anyone?

5.15 has been pulled from the downloads, it seems... (?)

SeaburyNorton

So can it be said (or confirmed by Mikrotik) that a upnp nat rule does not require a firewall filter rule that accepts it?

For instance, if you have a firewall filter rule to drop all forward chain packets from the internet interface, the upnp nat rule will accept them regardless?

SeaburyNorton

*bump*

Any other gurus agree/disagree with this method (above)?

SeaburyNorton

I use this method myself, and the accept rule is right above a "drop all" rule for the forward chain. All other accepts/drops are in the rules above it. I have not seen anything but packets from a port forward go through. This explanation was given to me by another networking guru. Althoug...

SeaburyNorton

It is my understanding that if you add an accept rule between two and three like this (assuming your lan addresses are 192.168.1.0/24): chain=forward action=accept dst-address=192.168.1.0/24 It will allow all of the UPnP rules through. This logic is that anything that is destined for your router fro...

SeaburyNorton

Thank you as well, NP! I assume if you've been using this for a while, you can verify that it does clean out the dynamic NAT forwards... This is what I use lately: /system scheduler add interval=1d name=resetUPnP on-event="/ip upnp set enabled=no;\r\ \n/delay 3000ms;\r\ \n/ip upnp set enabled=y...

SeaburyNorton

Thank you, fewi! Yes, you are correct inasmuch as UPnP creates dynamic NAT rules. I do think you're onto something with the second script line you wrote. What is being thought of, however, is some sort of pass/fail scripting. For instance, UPnP opens a dynamic NAT rule of udp3074. Machine that creat...

SeaburyNorton

BTW, a prime example of this is the Xbox360 vs. PS3. PS3 opens a upnp port in the NAT table, but when you shut the machine off it released the dhcp address and closes the port. The Xbox360 does not. It opens 3074UDP upon logging into LIVE and never closes it when turning the box off. To remove the p...

SeaburyNorton

How about a "script" for turning UPnP off and on every night to clear it ?

A kill and restart script is what I had thought of at first, it seems to work really well on other open source platforms. There has to be some decent way to do this in RouterOS.

SeaburyNorton

Time for another bump...

Of course a script would be lovely.

SeaburyNorton

Thank you so much for this excellent script! I've been looking for something like this for a while now!

I can confirm it runs quite well on ROS 5.4.

SeaburyNorton

That won't work. It simply doesn't scale. The built in caching resolver is fine for small scale but isn't a DNS implementation that can handle a few thousand to tens of thousands of static records. It also doesn't scale when you try to do this in more than one router. Build a proper DNS server, imp...

SeaburyNorton

I tried to research this very thing when I first moved from tomato to mikrotik last year. The only thing I could even think of would be to create a similar script to the ones found on the tomato forums that would somehow import these lists into the "static dns" list on a mikrotik box, all ...

Problem with Queues. We upgraded a core router from 4.x to 5.4.. The router (HP ML310) has some simple queues to smooth trafic flows.

SeaburyNorton

Nothing yet.

It's the typical 4-5 hour wait between the time they release it and it actually becomes downloadable.

SeaburyNorton

I too would like a version that works with OpenDNS. Anyone tried this yet?

SeaburyNorton

Any reply from Mikrotik on this?

Hello, all... thank you for your help in advance. I have two networks running on an RB450G.

SeaburyNorton

I was thinking along the lines of a script running with scheduler... anyone?

SeaburyNorton

It has been my experience that if you have multiple xboxs behind a firewall and with upnp enabled, each xbox will pick a port.

the first will pick 3074
the second will pick 6148

and so on. I've run 3 at a time.

This is definitely a video card driver issue... I updated the nVidia drivers and the problem vanished (this was a while ago).

Small point I noticed... I have a 450G running 4.16. I experience the "crash on reboot issue" occasionally. I can reboot with no problem MOST of the time, but the common factor I notice is this: Occasionally, when adjusting rules (mostly in ip>firewall>filter or >queue tree) in winbox, the...

I guess the difference is that I am running v5.

Hey, Normis...

So you would say this isn't something I should worry about?

SeaburyNorton

from your web browser access the router by IP. On the page that is displayed, download winbox. I would recommend upgrading to 4.16 first as it is the latest V4 version and it will include the latest recommended version of winbox downloadable through the web interface of the router board. I AM runni...

SeaburyNorton

Why would you downgrade your rb450g ?? the OS on that originally should have been v4 ( or possibly v3 ). You claim to be running a v2 ?!? EDIT: And how is it you have 520 MB ?!? Something is amiss...... I'm using 4.6 with version 2.2.18 of WINBOX. As for the amount of HD space, I couldn't say... th...

SeaburyNorton

This thread has had quite a few viewers... it couldn't be that I'm the ONLY one seeing this(?)

SeaburyNorton

This is what I'm seeing:

I'm thinking it has to do with a winbox version... I'm using the one downloaded from the mikrotik site, 2.2.16.

Update: Now using 2.2.18, still same result on resources page.

SeaburyNorton

do you have the routerboard package installed ?

Absolutely.

I'm not sure if it's affecting anything, it just seems odd.

Model field is blank but board name at the bottom says RB450G. All other fields populated.

SeaburyNorton

PS - It seems to have been this way through every version, since 4.11.

SeaburyNorton

I know these can be removed manually... anyone write a script for this?

SeaburyNorton

You have full control over what DNS server you hand out. Turn on the DNS server under IP > DNS, then edit the IP > DHCP-Server > Network settings and set the router IP address as the DNS server. Yes, you can enforce usage of that DNS server via a NAT rule. Assuming a WAN interface name of "WAN...

SeaburyNorton

I'd like the answer to this myself...

I know you can highlight and remove the dynamic entries, but there has to be an easier way... script?

Surely someone must know...

SeaburyNorton

On my RB450G running 4.16, when I go to system > resources in Winbox, the "Model" field is blank. Is this normal?

SeaburyNorton

Upgraded from 4.14 to 4.15 on RB450G. Upgrade seemed to have failed, router simply never came back. After 17 minutes I pulled the power and then plugged back in. Router seemed to boot up just fine with new 4.15 version after that.

Are we SURE the 4.14 boot loader bug didn't affect other models?

I used the second script on the page as I have manual entries as well that I didn't want disturbed. It uses the TTL difference to differentiate between the two types. Fantastic!

This is the default for OpenDNS. However, there is a solution: add dhcp leases to static dns in the router: http://wiki.mikrotik.com/wiki/Setting_static_DNS_record_for_each_DHCP_lease I think the second script on that page may help, I'm going to test it later!
