260GS OS rev 1.10 I am trying to set up a layer 2 link across a pair of 260GS switches connected by an SFP link. The fiber link is fine but there doesn't seem to be any ARP from the remote 260GS. In the diagram below all units are in the 10.49.5.0/24 network. 10.49.5.1 can ping 10.49.5.2 but not 10....

Do you have any Queues? Please post your config, anybody who sees this. Thanks!

No queues in use here. Very simple config.

I can confirm. We have the same situation. Spikes are at every 35 secs. 6.8rc1 does't repair a problem. We have this issue on RB1100Hx2, RB 1100 and RB2011. I can read before on any Polish forum that users have similar problems. We have it on RB2011 and RB750. We never upgraded the rest. Down gradi...

We recently upgraded a number of RB1100 from 5.21 to 6.7 and are now seeing spikes (!?) in both the real time byte/packet graphs and in the Tx/RX columns in Interfaces. They appear to be real because they seen by other devices upstream/downstream. The heavier the traffic, the bigger the spike. They...

I've got an RB750 I'd like to take back to 5.22 from 6.7. Copying the .npk file into files and rebooting doesn't seem to do the trick, what's the secret sauce?

There are 2 ways that I know of to do this, for real time, click on the interface in webfig and open it up, scroll to the bottom and you should have both a real time byte graph and a real time packet graph. For non-volatile samples, set up graphing (webfig->tools-graphing) add all interfaces. Can be...

that would be under your /ip firewall filter and you'd want to deal with it on the forward chain. bear in mind that filter foward happens after nat so IP addressing will be the translated address So I want to allow $IP1 $IP2 and $IP3 to 192.168.80.1 and disallow all others, what does that look like...

jt2048

So far you have an x.x.x.x./27 on your wan interface. Just add a /32 within that /27 onto the same wan interface then just program your src/dst nat rules accordingly just using that /32 as the src or dst address. Then you can map everything to a single host or break up the ports to multiple hosts j...

I'm trying to replace our head end Fortinets with MikroTiks and we've got most of that worked out however I need help with one final piece.

Suggest you hold off on downgrading if you...

Set their master port to none in the interface settings.

Sent from my SCH-I545 using Tapatalk

Yes, that's what I'd do normally but it doesn't show up under interface settings /webfig/#Interfaces.Interface.3, no master port shown (no gadget). I have no idea of how to do this from the CLI.

Winbox works fine but Webfig doesn't display active graphs during bandwidth test. Test itself is fine, just now graphs.

While the bandwidth test itself works just fine, the on page graph (and associated text info) shows no data while a band width test is running. Is this broken or do I have something misconfiguration?

The suggestion to put the /29 on LAN2 would mean that the IPs would be available directly on LAN2 ie a machine connected to LAN2 could be assigned an address in that range and not need any NAT. If you want to use NAT instead then you would assign all IPs to the WAN interface, and then add specific ...

You can just leave the word "export" out of the command. You will end up with more data to validate but the format will be the same. Ok, that seems to work. So edit the file to taste and then restore. How do I load that file on the new rb750 after uploading? JT Too simple, many thanks! JT

Make sure you are using at least version 5.12 and then run /export compact file=backup The data in the file is plain text.

Have one set up the way I want. Need to clone 2 or 3 more for a lab network. Did a search, read TFM, nothing very useful. Can I just backup one, restore the backup on another and edit the diffs? Or is there a better way. OBTW, what format is the backup file in?
