MikroTik

Hi!

I've been a routerboard user since 2007. I've had 4 different models and all have been working almost flawlessly since. I've updated them on occasion and had some hiccups - but nothing serious. I recently bought a RB2011UiAS-1HnD-IN for use at home (have a 433UAS at home) because I needed faster interfaces. 100mbit doesn't cut it anymore.

When I received it I wanted to reconfigure it to just be a drop in replacement (same ip range - and I wanted eth0 to be a local LAN port (have POE powering my RB433 on eth0) and my eth1 to be the wan port.

Said and done - I reconfigured the ports and it it works that way - but, in any way I try to change the default IP range to the one I am using at home - it just won't work. The quick setup page shows 0.0.0.0 sometimes, the default dhcp pool disappears even tho I don't touch it (reconfigure it to the range I am using). It stops giving out IP's after reboot and sometimes disappears too.

Now, my 433 was on 6.0 and was working perfectly fine. Don't know why I upgraded to the latest RouterOS on that one - now the 433 is showing similar signs. The pool doesn't disappear and all but the default IP range 192.168.88.1/24 was added to eth1 and is showing in the quick setup page - even tho my range is the one used. The funny thing is if I remove the default range - things stop working completely - just like the RB2011.

There must be some kind of default IP range bug in the latest RouterOS or I am doing something completely wrong (which of course might be possible too). Does anyone else experience the same kind of issues?

I am not sure if I am reporting this in the right forum section. I have not been active here before because I haven't had any real issues that needed any interaction - but this thing just baffles me.

The biggest difference with the 2011 is that it has hardware-switched ethernet interfaces. It uses bridge-local as the default "lan" interface, with ether1 as the gateway.

You should be able to go into IP Addresses menu, and change the LAN IP to 192.168.1.1/24 (just modify the existing address) and then go modify the IP Pool for DHCP, and the dhcp-server > network.

Changing those items should be all you need to do to use whatever LAN IP range you like.

ZeroByte,

I have a RB493 as well, which is hardware switched and i've not had these issues. As you can see, I am having a similar issue on the RB433 which is not hardware switched.

I've done exactly what you're describing (changing IP), but it's not working for me. I've done it with and without changing WAN ports. As soon as I change IP, things start to act up and ends up not being able to access anything besides connecting using MAC address and winbox.

Last try, I actually just added my range and kept the default, then added a pool - and assigned the pool to that interface and it seems like that works - but removing or changing the default won't.

So, I figured it out. Apparently - changing ip requires you to add all configs for the new IP and delete all old - else something doesn't work out as it should. Not sure why/what.
