Packet Filter PoliciesSecurIDRSA SecurID Two-Factor Authentication give more security to the user authentication procedure. Createdby Security Dynamics Technologies, Inc., it uses SecurID tokens to generate codes and ACE/Serversoftware to corroborate the codes.Characteristics• Internet Protocol(s): TCP and UDP• Port Number(s): TCP 5510, UDP 5500SMB (Windows Networking)Windows uses Server Message Block (SMB) to share files, computers, printers, and other networkresources.If you set up replication, you can see many tries to use the port mapper service on port 135. When thisfails, SMB begins to use port 42. Refer to the RFC for DCE, and the DCE-RPC proxy sections for moreinstructions.NoteSMB through the Firebox is not secure and we do not recommend it, unless used through a VPNconnection. These configuration settings are to be used only if there is no other alternative, and policysettings must specify internal and external hosts.Characteristics• Internet Protocol(s): TCP and UDP• Port Number(s): UDP 137, UDP 138, TCP 139, TCP 445, UDP 445SMTPThe SMTP packet filter policy allows SMTP traffic (e-mail) without using the SMTP proxy.Characteristics• Internet Protocol(s): TCP• Port Number(s): 25SNMPSimple Network Management Protocol (SNMP) is used to collect information about and configureremote computers. This can be dangerous. Many Internet attacks use SNMP. Because SNMP can causechanges in a network if enabled, carefully review alternatives and record logs for all connections.Characteristics• Internet Protocol(s): UDP• Port Number(s): 161392 WatchGuard System Manager
