Hi Christian, Thank You for answer.
This is my problem: I have a range of public IP address assigned to my DSL connection and I use a MT (PPPoE server) for user authentication.
When some user start connection must obtain public IP address from MT.
Now I'm trying your suggestion but I'm sure to mistake something...
I've created a pool with public IP range (example from 100.100.100.150 to 100.100.100.200) then I've activated PPPoE server. My test MT have a wan card connected to DSL router and a wlan card for user access. The IP assigned of wan card is 100.100.100.99 and gateway is 100.100.100.98. When first user start connection PPPoE server assign it the 100.100.100.150 IP address, for the second user the IP it's 100.100.100.151 etc. but all users exit on the public network with same address 100.100.100.99 (wan card IP address). I need every user exit on network with assigned address, the first with 100.100.100.150, the second with 100.100.100.151 etc. I hope You understand what I want to say, my english isn't good. In other words, every user receive right address but don't exit on public network with this, every user have the same address on public network. There is a solution for my problem?
Thanks to anyone want help me and Thank You again Christian for answer.
