Levels of security
Choose one of the following levels of security:
• --high
• --medium
• --disabled
--trust device
Listing a device here, such as eth0, allows all traffic coming from that device to go
through the firewall. To list more than one device, use --trust eth0 --trust eth1.
Do NOT use a comma-separated format such as --trust eth0, eth1.

• --dhcp
• --ssh
• --telnet
• --smtp
• --http
• --ftp
--port portspec
You can specify that ports be allowed through the firewall using the port:protocol for-
