I have an interesting scenario for which I am not sure there is a solution. I have a 3Com chassis running Hiper ARC (ver 5.3.105) and a number of Hiper DSP cards (ver 3.5.13). The requirement essentially is to have users assigned an IP address based on the port they dial into on the NAS. I have setup 2 separate IP-pools on the Hiper ARC, and have setup 2 different modem-groups. Each of the modem-groups is associated with a separate dial-in number. Is there a way to link each modem group to its own IP-pool on the NAS? I have seen that the either of IP-pools can be prioritized, or set up for a round-robin usage but this is essentially not going to solve the problem.

I think a solution may also exist where radius assigns an IP address from separate IP pools based on the user who is connecting. Any insight into this?
