RB2011UiAS-RM with 6.30.4 OS can't connect to internet

Mon Apr 25, 2016 7:37 pm

Hi,

we have just bought a RB2011 can I am trying to configure it with a Virgin SuperHub 2 (BUS_V2.37.13). I have put the SuperHub in modem only mode, and when I plug the ethernet cable into my laptop I get an IP address from the Virgin DHCP server and can connect to the internet.

However, when I plug the ethernet cable into the RB2011, I get a different IP address and I do not have an internet connection. The IP address assigned to the RB2011 ether1 interface is a Virgin one, according to ip-lookup.net.

I have tried setting the IP address to static and entering the same settings that my laptop receives, but this doesn't work either. I have also tried changing the MAC address to match the SuperHub's WAN modem address but this results in no connection whatsoever.

I have been through the initial config here http://wiki.mikrotik.com/wiki/Manual:In ... figuration and the IP/Firewall/NAT and IP/Routes seem to be fine, however I cannot ping the gateway IP from the Tools/Ping command.

Can anyone help with this?

thanks
James

Hello,

This setup is quite simple.

You should receive an ip address from your modem in ether1(mikrotik side) (in your dhcp-client). Check if default route in checked.

Then, you should have a NAT rule (masquerade) out-interface=ether1.

Then, you should have a default route to the ip address of your modem.

Try to ping 8.8.8.8 from the terminal of your Mikrotik. If it works, try to ping google.com.

If it does not work, check /ip DNS if you have configured DNS Server.

Regards,

Thanks, it appears that the SuperHub is not working with my laptop now, when it's in modem mode. Looks like it won't work that way for some reason. I have now turned off Wi-Fi and the DHCP server and have set the IP address as a default gateway on the RB2011.

I now need to set up another SuperHub on another interface but the only available interface seems to be sfp1.

How can I do this?

OK, so you need something like this : https://www.roc-noc.com/mikrotik/router ... -RJ01.html

So that provides another ethernet socket on the front right? Is it not possible to use one of the other sockets on the front of the unit?

It depends how many Ethernet ports are used. What kind of socket are you talking about?

Well there are 10 ports on the router and I want to set up 3 of them as WAN ports with load balancing and use another one to connect to an external switch, assuming this is possible?

Maybe stupid question, but did you delete default config of 2011?

I am connecting to the RB2011 via ether5 at the moment so I think I will lose connection to the router when I delete the default config? I think this is the problem I had before, so I am trying to work with the default config.

Or is there another way of connecting to the unit? As far as I know, there is no serial port on the unit (I am not in front of it at the moment) but I am pretty sure it is the same as this on the back:

The front panel just has micro USB, SFP, 5 x gigabit ethernet and 5 x fast ethernet. I believe the USB port is only for external storage/or 3G/4G modem? This post would seem to confirm that, but I am fairly certain there is no serial port on the back of the unit.

Is there another way to connect if I delete the default config?

Yeah, you can connect via winbox, using MAC address.

Thanks, I have got WinBox working on my Mac with Wineskin.

My current config is below. I now have a working internet connection, but how can I configure load-balancing for the second internet connection? Or even test that it is working?
