Having had 2 Orcon routers fail, I am trying to set up a MikroTik RB750GL to replace the Genius modem. I don't use the Landline/SIP so no issues there.

so far I have managed to extract the PPPoE password from the old white orcon router. Decoded it from base 64.

Added VLAN ID 10 to the ether 1 WAN port.

The PPPoE won't connect.

Anything else that needs to be set?

I am aiming to have this as a router and DHCP server for my home network.
Thanks,
Paul

UFB? We don't use PPPoE, you'll get a DHCP address on vlan 10. No auth required (it is port based). HTH.

Helps a lot thanks.
Much wrangling with the RB750, eventually used sbiddle's guide to turn it just into a bridge to do the vlan tagging with an old netgear router I had, success. I believe it should be possible for the RB750 to do both jobs, but not worked that one out yet. Will try another day.
Hopefully one of the clever people who understand the setup of MikroTik routers will be along and nudge me in the right direction.

Check this:

I'm thinking of a mikrotik myself as I want a more involved setup, so will be interested to see how it goes

I think I could set the dhcp client to listen on the bridge or vlan and then put the dhcp server onto eth2 (and nat/firewall)
Will try that another day though.

Ta.

That guide is not how I'd do it either

Just modify the default configuration.

DonGould, can you be a bit more specific than that? I tried to modify the default settings with no luck.
The guide in summary states:
create vlan on eth1 (key setting is vlan id of 10
create bridge
add vlan and eth 2 as ports to the bridge
connect eth1 to ont and eth2 to router.

my next test will be to try to add DHCP client (set to automatic) to listen on the bridge, DHCP server on eth2 with eth3-5 slaves to eth2 (default). And add in NAT if not already set.

How would you do it different?

Bingo.
DHCP Client listening on bridge.
DHCP server on eth2
NAT set to the bridge.
connection!

Now just need to work out how to set reserved addresses in the DHCP setup...

That's better:

Was getting about 90-95 up with the Genius white when it was working, about 85 with Genius black, 47-49 down.

With the old Netgear was down to the 40s down and teens up.

Hate to burst your bubble slightly but the NF4V is more than capable of routing several hundred Mbps from WAN to LAN without breaking a sweat. The cause of a few Mbps difference is not that the Mikrotik is "better".

I use both on a daily basis, and while as a router Mikrotik hardware is a lot more capable, from an end user perspective it's a few steps backwards. In all seriousness it will take somebody who has a good understanding of networks at least a few weeks to really grasp the basics of RouterOS.

For an average end user CPE I'd never deploy a RB750GL over a Netcomm NF4V (and that's me saying that with large numbers of both Netcomm and Mikrotik devices in use)

I hope you're correctly configured your firewall with a blocking rule or you'll probably have wide open DNS resolvers.

drpaulmartin: DonGould, can you be a bit more specific than that?

open winbox and connect to the router
files backup
system reset configuration
interfaces --> plus button --> add vlan to ether1 - set tag to 10
ip - dhcp client - choose the default entry, change the interface to listen on your vlan
ip - firewall - nat - change the default entry to nat your vlan interface not ether1
ip - firewall - filter rules - as above. change every entry that is filtering eth1 to filter your new vlan

done

sbiddle: I hope you're correctly configured your firewall with a blocking rule or you'll probably have wide open DNS resolvers.

agreed, which is why you use the default configuration and modify it because it comes with the basic firewall which only accepts related/established connections.

failing this, google "rb750 default firewall" and follow your nose, but it will give you the same basic answer.

Agreed.

As he has the box now he may as well get busy and make it sing, but if readers are choosing then Mtk is not a consumer friendly option, but I can't recommend a geek having a hack highly enough!

Sbiddle - thank you for your input, and your guide which got me started. the term "better"is different to different people. as a box to roll out to every average customer I agree that the white router is definitely a lot more user friendly. For my case however the router I had was starting to drop through put for a few seconds at a time which made my wifes skype conversations with her mother drop. Went through orcon support. did all the resets etc they asked. they then watched the connection for a short while and told me it was fine. I had logs of repeated pings showing the drop outs... it wasn't fine. I had the black router from a previous install and switched that out. but there was still the occasional issue and needing reseting, which is why I looked for something better as I didn't relish the thought of going through Orcon support, to try and get another white router. Hence the pick up of a RB750GL, mainly promted by your guide. I appreciate that a few more Mb through put does not make it the cure for all disease, but for me it seems like it will do the job and be reliable which is what I am after. It is a pig to configure for a minor dabbler in networking.

DonGould - Thank you. So the bridge is not neccesary... ok. The default firewall is set to drop all incoming at the moment. That will do for now. I will work out how to open up specific ports later and forward them where they need to go.
