Re: Redirect HTTP for PPPoE users with radius attribute

I'm thinking about it, but how can I make dst-nat for only specific users?
Set up a chain which will be used as "Filter-Id" and set action to "jump=dstnat" - will this work?

Remove unneeded items in Tools - Graphing - Interfaces

Hello.
I've accidentally set "all" in interface graphing rules, but when I removed it, there's still a list of all dynamic interfaces in graphs.
And it still collects all this data.
How to remove everything or just unneeded interfaces?

Re: Clustering RouterOS PPPoE Servers

3.7 beta works fine, as we can see for this short period of time:

Re: PPPoE server performance and packet lose problems

Do you use queues? We have the same problem with packet loss and one of the problems is that ROS drops a packet every time a queue is created or deleted. When many users connecting/disconnecting you get a packet loss. Maybe that's not the only reason, but thats a reproducable and Mikrotik confirmed ...
