Is the rule user- or group-based? If so, secureNAT clients will be blocked for a lack of authentication.

[no firewall client] They can access everything fine until I add a rule to block a particular destination set. After that, they can't access telnet [port 23] it just stops dead. My windows 2000 pc's can telnet fine still [they have the firewall client installed] Anyone have any ideas ? I am totally lost.
