Is Fasttrack supported on a RB450G?

This seems to imply no https://wiki.mikrotik.com/wiki/Manual:IP/Fasttrack

I do have the "Allow Fast Path" checkbox under IP < Settings which is why I'm a bit confused on it being supported or not.

Thanks for getting back to me!

Try to drop output; it seems to be skipping forward, and I think if the router originates the packets, it will place directly at output chain. Packets come in from the WAN-BRIGDE (this bridge contains the WAN interface uplink to a cable modem and it also contains VLAN20). By the way, it is a CASA C...

For anyone wondering about this in the feature, here is the answer from support:
CPU freuency and usage is not proportional to throughput, never was and never will

CPU usage percentage incorrect?

So I set my CPU to 100 MHZ. At that point the router can route + nat about 10 megabit (I can go to about 40). Strangely, the CPU indicates it is being used for about 30%. Same usuage then when it is on 680 MHZ. So I could conclude the CPU is not being maxed out at 100 MHZ but the fact I can only get...

Re: How should NTP-server behave?

If the stratum of Windows is 2, it will not accept the Mikrotik as a more reliable source. I had that issue first:). That kind of resolved itself after a reboot (Windows reboot that is). The Mikrotik has stratum 3, and Windows now (correctly) says it has 4. My question is specifically with the large...

How should NTP-server behave?

I've set up NTP-client on my RouterBoard 450G and it is synchronised with a server. Then I installed the NTP-server package and configured it as follows: /system ntp server> print enabled: yes broadcast: no multicast: no manycast: no My Windows client update just fine from the server but I've notice...

Re: Firewall logging not working as expected

I'm thinking UPnP is kind of risky. I briefly tried it and couldn'd be bothered to make it work. You are correct about the XBOX 360 not needing a "full DMZ host", I could simply look up the specific ports it uses. However, I've puzzled a script together that appears to be working. It's far from perf...

Re: Firewall logging not working as expected

That destination NAT rule forwards all new connections established from the WAN to your WAN interface to 192.168.0.5. It does that by changing the destination IP address from your public IP to 192.168.0.5. At that point the destination IP address is no longer an IP on a router interface, so that tr...

Re: Firewall logging not working as expected

Alright :) , I've made some progress. I've determined what part of the config is causing my problem. I wanted to set a game console as DMZ. The problem with this is, is that my WAN interface has a public IP. This IP is dynamic. So I could not specify a destination address for the dstnat chain: Flags...

Re: (tagged) VLAN high level configuration question

Valid points although for (1) the RB450 and RB493 should be able to do this (you can divide the switch chip). Doesn't make all too much sense since port count is pretty low.

and (5) is a really cool option.

Re: (tagged) VLAN high level configuration question

What features are you missing? if you check out http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features the Atheros8316 seems to be a fully featured switch chip. And I do agree entirely, using the routerboard just for routing (or inter vlan routing) is more powerful yet less complex. I know L3 swi...

Re: (tagged) VLAN high level configuration question

Indeed, just enabling them made everything work. Many thanks for helping me achieve this. Something I found out is, that if you want more ports of the Mikrotik in VLAN 10 (internal lan) you must: 1) create a bridge 2) assign an IP to that bridge 3) assign VLAN 10 to the bridge 4) assign any port you...

Re: (tagged) VLAN high level configuration question

Darn, I've setup the VLAN thing and no dice. Could you please take a look for potential errors? I had internet access _before_ I configured the VLANs, so most of this works apart from the actual VLAN stuff. On the cisco I put a port in VLAN 10 (access port) with matching PVID 10 and I configured the...

Re: (tagged) VLAN high level configuration question

Most interesting topic this is. It all looks so easy, in theory. Basically what VLANs are is a way to logically divide up the same hardware so each section acts as it's own independent piece of hardware where one VLAN cannot see or talk to another VLAN. So with an untagged port any traffic leaving t...

Switch chip VLAN

Continuing my VLAN experiments, I've realised switching will give me full wire speed and bridging won't. Right now, I've got a 4-bay NAS connect and a 20-bay NAS connected to my network. One of both might end up on the MicroTik switch so wire speed will be a real plus when the 4-bay unit is being ba...

Hey everyone, I just got my MikroTik device and I'm very excited. I've just created a WAN-port which asks DHCP from my cable modem (=asking a public IP)and I've assigned the remaining 4 LAN ports to a bridge. My internal 192.168.x.x/24 network is being NATTED just fine. I owe the wiki and forum my t...

Re: 450G question about NAND memory + POE interface

So we can't brick the unit that way. That's a good thing.

Will it affect the license? There are some posts saying it does, and others saying it does not.

Re: 450G question about NAND memory + POE interface

HDD is another word for NAND(meaning storage here) then. 1 GiB for the OS :shock: isn't that total overkill? Oh, sorry I didn't connect the HDD to the NAND thing.

Can you find any reference connecting that 64 MB to the bootloader? It would make sense though.

Re: 450G question about NAND memory + POE interface

@InoX, I can see the SDRAM, 256MB. That's just the system memory as it is used in computers.
But I'm trying to figure out the purpose of both the 512 MB NAND and the 64 MB NAND (both mentioned in the PDF I linked to).
