I think you could do this without involving a DHCP server (can a PPP connection even use DHCP??). Their is a module rlm_ippool which looks like it would do what you want. I haven't used this since I haven't needed multiple pools, but it looks like it would work. In radiusd.conf something like: ippool fake { range-start = 192.168.1.1 # I assume you are meaning range-stop = 192.168.1.254 # RFC1918 space when you netmask = 255.255.255.0 # say faked. cache-size = 254 session-db = ${raddbdir}/db.ippool-fake ip-index = ${raddbdir}/db.ipindex-fake override = yes maximum-timeout = 0 } ippool real { range-start = 10.10.10.1 range-stop = 10.10.10.254 netmask = 255.255.255.0 cache-size = 254 session-db = ${raddbdir}/db.ippool-real ip-index = ${raddbdir}/db.ipindex-real override = no maximum-timeout = 0 } And in users something like: guest User-Password := "guest", Pool-Name := "fake" Service-Type = Framed-User, Framed-Protocol = PPP DEFAULT Auth-Type := System, Pool-Name := "real" Service-Type = Framed-User, Framed-Protocol = PPP I have not tested any of this, it may cause Bad Things(tm) to happen, adjust accordingly to use the correct IP ranges, etc. #include <standard-disclaimer.h> Michael ---------------------------------------------------------------------- Michael J.
