Hi, how can I achieve, that the radius-server is replying IP-address A, if comming from NAS A, and IP-address B, if comming from NAS B? Altough: IP A is stored in LDAP as IP-A and IP B is stored in LDAP as IP-B But unfortunately I do only have one Framed-IP-Address-attribute which should be mapped to either of above, depending of the NAS-IP. Any Ideas or further reading? Thank you! Regards Florian -- Dipl. Inf.
