Hello, I have a question about the following inbound Cisco ACL entry... access-list 100 permit udp any X.X.X.0 0.0.0.255 gt 1023 From what i understand so far is that this entry is required for normal outbound ftp,tftp,dns, and traceroute traffic. It has been suggested that one should specificly add deny rules for common UDP ports above that range. My question, I am looking for suggestions to make that more restrictive ? What problems would there be with other hosts on the LAN if the entry was removed ?
