There’s MikroTik 750 GL in our office, configured by my ex colleague. I’ve logged in to web config, and tried to set up port forwarding on port 80 to a particular destination on the intranet. Now, when I went to NAT, clicked add new, setup everything, and clicked OK, it complained “couldn’t add new nat rule outgoing interface matching not possible”.
After that it appears to have logged me out, and when I tried logging in back again via web interface, error says router is disconnected. I also tried winbox, it says not reachable. Aside from that, I now can’t access anything on the internet nor any websites( IIS ) in intranet.
So, is there any way to revert what I did or, given I can’t log in anymore, I will need to hard reset router?
How long since your last MTCNA course?
Monkeying with a new config that you didnt setup is a MINEFIELD…
The first thing one should do is
a. create a backup file
b. export the config and export a verbose config and export a show sensitive config (for passwords etc.).
@anav,
in this case common sense is lacking…
webfig is used on a browser,
the browser uses port 80…
what happens if I redirect port 80 elsewhere ???
goodbye webfig…
Well now that you put it less delicately than I, yes a bonehead bozo move for sure LOL,
I was trying to say nicely… what makes you think you are qualified to touch an unknown MT config LOL.
Yeah, I know all this. I am to be made fun of for trying to set up something I know very little about. I am to be blamed. Can you just help me figure out how to use winbox to connect via mac address?
Of course, we are big on accountability here. Why go mucking about on a work router, when you really dont know anything about it.
If you are part of IT staff then your training should have dictated otherwise,
If this is a small business, where one has to fend for oneself, then instead of losing down time, connectivity and perhaps business, its probably prudent to actually look for professional help.
The forum is great for non-critical and non-time sensitive issues. https://mikrotik.com/consultants
We can help as best we can, but with it comes directness and truth…
Thanks for the tip on MAC address. I managed to get in, but got this notification:
The following default configuration has been installed on your router:
ether1 is renamed to ether1-gateway
DHCP client and masquerade is set on ether1-gateway
ether2 is renamed to ether2-master-local and configured as switch master port for ether3-ether5
IP address 192.168.88.1/24 and DHCP server is set on ether2-master interface
DHCP servers address pool is 192.168.88.10-192.168.88.254
You can click on “Show Script” to see the exact commands that are used to add and remove this default configuration.To remove this default configuration click on “Remove Configuration” or click on “OK” to continue.
NOTE: If you are connected using the above IP and you remove it, you will be disconnected.
Is that a standard notification, or somehow or for some reason these changes have actually been made?
Ie. why is it showing this? I just logged in, didn’t touch anything. Does this mean additional stuff is going to be changed compared to when I first messed up, or is this something I should ignore?
“ether2 is renamed to ether2-master-local and configured as switch master port for ether3-ether5”
Bruh, you traveled back in time! Master/Slave switch config is deprecated since a few good years now.
And by that message you (or someone else) managed to reset the device. Or you logged in on another device by mistake.
Are you sure that you know what you’re doing?
So, as I said, I logged in via webconfig, made a mess and haven’t been able to login since then. Now, I just started winbox, logged in and I got this message. Didn’t do anything except for that.
Should I click ok, ie continue with that default config, or should I click remove configuration. Will latter restore original config that was there prior to me logging in?
That message usualy shows up after a device reset, like I’ve said above, if you accept that config, any (if any) config currently on the device will be replaced with that one showed.
If you select remove, you’ll end up with no config.
But from what you’re telling us, it’s dead anyway.
Look for backups in Files, try to rebuild from there, I don’t know.
Or redo the config if you have all the wan/lan details etc. @anav master/slave was deprecated in 6.41, 22.12.2017. So he’s on something even older.
It’s v5.9. I will hire someone to fix all this mess but need to make sure tomorrow everything is operational, ie as it was today, so can’t really risk with upgrading router now. Can you tell me about this default config? The notification says it’s already added, if I understand correctly. What happens if I click remove configuration? Or should I just go with it and try to set it up as it was before?
Thanks.
