Radius local ip address

RouterOS General
1

I have several hundred static ip customers

How can you tell (using radius) the router what local ip address to use?

If some of the customers use 192.168.1.x, and others use 10.0.75.x the router complains (after getting auth and a ip from radius) it does not know what local ip address to use, any suggestions?

It’s not a supported Radius Attribute. MT should perhaps look at adding it to the dictionary.

For now, just assign the local IP address to the default group that your PPP service use…

Yeah done that, it works fine if you only have 1 subnet,
At least I now know it’s not something I missed, and I hope to see this attribute in the next version.

MikroTik staff, is this somthing you can add?

Just FYI… Then you have another configuration issue somewhere… PPP is Point-To-Point. It doesn’t care about a subnet (netmask is 255.255.255.255). If you’re local IP is 192.168.1.1 you can assign anything from to the remote client and it will work - provided the rest of your network is configured to accommodate it.

If you’re assigning a subnet to your remote clients, then local IP will become a issue as it needs to be in the same netmask as the one you give your clients - but there’s better ways to do that instead of PPP… VLAN’s come to mind as one possible way…

If you need more than one Class C for your PPP clients, use super netting. 255.255.254.0 for example, gives you two Class C networks to use (192.168.0.1-192.168.1.254 for example)…

Right you are, All I needed to do was put a local address in the default profile for the pppoe server and everything works great.

Thanks for your response.
