Default Settings For System Activity - McAfee FIREWALL 2.1-GETTING STARTED Getting Started

McAfee Firewall Configurations

Default settings for System activity

NetBIOS over TCP: Blocked
This will block all fileshare activity over TCP as well as UDP broadcasts. Your
system will not appear in anyone's "Network Neighborhood" and theirs will
not appear in yours. If your system is configured to support NetBIOS over
other protocols, such as IPX or NetBEUI, then filesharing may be allowed if
"non-IP protocols" are allowed (see "Other Protocols" below).
Identification: Allowed
This service is often required when getting email and is required by most IRC
servers.
ICMP: Blocked
This protocol is often abused as a method of breaking people's network
connections (especially on IRC).
ARP: Allowed
ARP is a necessary Ethernet protocol and is not known to be a threat.
DHCP: Allowed if your system uses DHCP
The program looks in your system Registry to see if one of your network
devices uses DHCP. If so, then DHCP is allowed for all devices. If not, then it
is blocked for all devices. If you have more than one network device and one
uses DHCP, you should check the DHCP setting for each device and allow
only for the device that uses (most often cable or ADSL modems and some
internal networks, not for dial-up).
RIP: Blocked
Allow RIP if your adminstrator or ISP advises you to.
PPTP: Blocked
This should only be altered by the administrator.
Other Protocols: Blocked
If you are on an IPX network, you should allow "non-IP protocols". If you use
PPTP, you should allow "other IP protocols". Ask your network administrator
before making any change here.
