PPPOE SUBNET Not Consistent

Hardware MikroTik hardware general
1

Using a Routerboard with Microtik software.
as a PPPOE Concetrator. it authenticates fine and all the customers are up and running.. IT is authenticating Public number NOT Nat’ing.
the subnet the customers get should be 255.255.255.255 or the actual subnet of the /26 that they are on.. 255.255.255.192

I noticed that some of the customers are getting
255.255.255.240 or 255.255.255.224

This is odd.. it still works because the pppoe terminated at the microtik but I don’t want them to be able to see other users …

Is their a place to set this in the microtik? I tried setting it in radius and it didn’t make a difference..
Thanx

I am getting worse. I get a subnet of 0.0.0.0 - I must be doing something WRONG

I think it just guesses a subnet size and displays it. The guess must be on how far apart the ips are. If they are consecutive IPs, it probably prints /31, if they are 33 ips apart it probably prints /26.

I don’t think subnet size is relevant to the customer since it’s a ptp connection and it’s working.

It should have a /32 255.255.255.255
