multiple sessions with static IP assignment

Hi, I have the following situation: each user can have 2 simultaneous sessions, but they must have static IPs (consecutive) for both sessions. For example, "users" file entries would look like this: test1 Cleartext-Password :="test1", Simultaneous-Use := 2 Framed-Ip-Address := "192.168.0.1", (other reply attributes...) test1 Cleartext-Password :="test1", Simultaneous-Use := 2 Framed-Ip-Address := "192.168.0.2", (other reply attributes...) Is something like this possible ? thanks, Flamur
