JP1110, Doing this opens up all services to all IP addresses again.  The context for the Dell switch is: permit service any I can say: permit ip-source [A.B.C.D] service tftp or permit service tftp However, neither one of these statements anywhere in the access list will allow TFTP to function. I ended up fixing the problem by allowing the IPs I wanted to access specified services to access all services: permit ip-source 10.10.0.25 service anypermit ip-source 10.10.0.26 service anypermit ip-source 10.10.8.25 service anypermit ip-source 10.10.8.26 service anypermit ip-source 10.20.0.25 service anypermit ip-source 10.20.0.26 service anypermit ip-source 10.20.8.25 service anypermit ip-source 10.20.8.26 service anypermit ip-source 10.10.0.230 service sntppermit ip-source 10.20.0.230 service sntpdeny service httpdeny service telnetdeny service snmp Thank you for your help!antsman
