Hi Alan,
Thank you for your email. The users used to get a vlan tagged with their DHC request I guess.
DHCP doesn't do VLAN tagging. DHCP doesn't *know* about VLANs. I'm saying that if the user is in the wrong VLAN, then they're in the wrong subnet, and the DHCP server assigns them addresses from that subnet.
That was how I think the old dhcp server was able to issue ipaddress on X and Y scopes. I see no traces of 2 VLANS mentions on any of the Free radius config files. This set up was working fine before the windows server upgrade. Is there a definite way to check if there are any VLANS assigned for the Authenticated users? I have access to the Radius server but do not have access to Homeserver. I hope the above makes sense.
Look a the RADIUS packets using wireshark. Alan DeKok.
