你可以更深地应用<command> /?，比如netsh advfirewall firewall /?，会导致'netsh advfirewall firewall add /?`，从而导致
I:\>netsh advfirewall firewall add rule /?

Remarks:
- Add a new inbound or outbound rule to the firewall policy.
- Rule name should be unique and cannot be "all".
- If a remote computer or user group is specified, security must be
authenticate, authenc, authdynenc, or authnoencap.
- Setting security to authdynenc allows systems to dynamically
negotiate the use of encryption for traffic that matches
a given Windows Firewall rule. Encryption is negotiated based on
existing connection security rule properties. This option
enables the ability of a machine to accept the first TCP
or UDP packet of an inbound IPsec connection as long as
it is secured, but not encrypted, using IPsec.
Once the first packet is processed, the server will
re-negotiate the connection and upgrade it so that
all subsequent communications are fully encrypted.
- If action=bypass, the remote computer group must be specified when dir=i
n.
- If service=any, the rule applies only to services.
- ICMP type or code can be "any".
- Edge can only be specified for inbound rules.
- AuthEnc and authnoencap cannot be used together.
- Authdynenc is valid only when dir=in.
- When authnoencap is set, the security=authenticate option becomes an
optional parameter.
Examples:
Add an inbound rule with no encapsulation security for messenger.exe:
netsh advfirewall firewall add rule name="allow messenger"
dir=in program="c:\programfiles\messenger\msmsgs.exe"
security=authnoencap action=allow
Add an outbound rule for port 80:
netsh advfirewall firewall add rule name="allow80"
protocol=TCP dir=out localport=80 action=block
Add an inbound rule requiring security and encryption
for TCP port 80 traffic:
netsh advfirewall firewall add rule
name="Require Encryption for Inbound TCP/80"
protocol=TCP dir=in localport=80 security=authdynenc
action=allow
Add an inbound rule for messenger.exe and require security
netsh advfirewall firewall add rule name="allow messenger"
dir=in program="c:\program files\messenger\msmsgs.exe"
security=authenticate action=allow
Add an authenticated firewall bypass rule for group
acmedomain\scanners identified by a SDDL string:
netsh advfirewall firewall add rule name="allow scanners"
dir=in rmtcomputergrp=<SDDL string> action=bypass
security=authenticate
Add an outbound allow rule for local ports 5000-5010 for udp-
Add rule name="Allow port range" dir=out protocol=udp localport=5000-5010
action=allow
