WatchGuard Firebox SOHO 6.1
Configure Incoming and Outgoing Services
By default, the security stance of the SOHO 6 is to deny incoming 
packets to computers on the trusted network protected by the 
SOHO 6 firewall. You can selectively open your network to certain 
types of Internet connectivity. For example, to set up a Web server 
behind the SOHO 6, you add an incoming Web service. 
It is important to remember that each service you add opens a 
small window into your trusted network and marginally reduces 
your security. This is the inherent trade-off between access and 
security.
Pre-configured Services
Each service is defined by a combination of Internet protocols and 
port numbers to uniquely identify the connection type to 
applications and servers on the Internet. The SOHO 6 
configuration pages include several of the most common types.
