MLPPP on CRS125-24G-1S-2HnD-IN

RouterOS Beginner Basics
1

I have 2 ADSL modems and may get a third line in the spring… I will have a static IP later this morning.. Currently running OPENWRT MLPPP and 4 other switches/Routers..

Hoping to consolidate things and get off the no longer archaic OPEN WRT I picked up a CRS125-24G-1S-2HnD-IN and

I’m trying to follow 3 year old instructions for an RB 750 and getting nowhere fast..

Log into the device, be sure to be plugged into Port 2

Using winbox go into Interfaces
Set the Master Port for ports 1 through 4 to none
Click plus to add a new interface, choose PPPoE Client
On the main screen set the MRRU to 1480 (by default its blank)
At the bottom you can add ethernet interfaces to the PPPoE interface
Add the interfaces 1 and 2 (if you have 2 lines, add ports 3 and 4 if you have 3 or 4 lines to bond)
Go to the dial out tab
Put in your username and password
Click ok

Go into IP → Addresses
Set the port to have the IP address (default is 192.168.88.1) to Port 5
Plug your ethernet into port 5.
Go back into Winbox
Go to IP → Firewall
Go to the NAT tab
Double click the default rule
Set Src address to 192.168.88.0/24
Set Dst address to 192.168.88.0/24
Set Out Interface to the pppoe interface
Click ok.

You are done.

If you need DHCP
You’ll need to go to IP → DHCP Server
Double click on default server
Change the interface from port 2 to port 5.

Unplug the device (power)
Hook up everything (properly)
Plug in the power.

Wait a few mins and should be all good.

I can get the Router/Switch to talk to the modems and I can get them connected..

What I can’t get is the computer to see the internet and I’m not sure they are bonded (I will check that)

Are there a set of reasonably generic instructions for my setup..

Those instructions won’t really help for this. If you can provide a network drawing with IP addresses, it would be easy to walk you through this.

Hope this is clearer then mud..

Essentially what I have is 2 6Mb ADSL modems (MLPPP with a fixed IP) coming in. The 3rd line is ordered and will be installed once the ice clears enough to run the lines.. (AKA not that soon there is 4 inches (10 cm) of ice under the snow)

I have a local network with about 25 devices Some of the devices/services I would like to access from the outside world via a port number.. And at some point I will likely need to do some Prioritization but that can happen later..

I really don’t care about the internal numbering I’ve been using 192.168.1.x because it’s what I started with.. But the network is small enough that if someone gives me a reason to use 10.x.x.x I could change the 6 or 8 machines that have fixed IP’s and update my hosts files in an hour or so. I don’t know that I want to look at IPv6 yet..

Currently the modems come into a TP LINK running OPENWRT and that goes to a an ASUS RT-11U (running DD_WRT) and then to 2 8 port switches and an access point 1 floor down.. (more because I needed to hard-wire the printer not because I need the Access Point.) All but my mini and it’s console run off the 8 port switches.. Aside from the OPEN WRT MLPPP not being supported anymore and having more holes then the Bismark the wiring for both the network and power is a bit of rats nest.
