Freeradius + Mysql

[L U C A S]

How do I deny access to a specific group of users in Mysql, using Nas-Ip-Address or Called-Station-Id?   I have NAS1 for dial-up access and NAS2 for cable, but user�s from NAS1 can connect in cable. It�s wrong, ok??   Help me.     Lucas   PS: In radgroupcheck I put ('1',dial-up,'Nas-Ip-Address','==','my-NAS-ip') and don�t work.
