Blocking External Sites
By default, the security stance of the SOHO is to deny all incoming packets from the Internet to computers on the trusted network protected by the SOHO firewall. However, if a user initiates contact with an external site, the return traffic will be allowed through the firewall. You can selectively close your network to certain Internet sites entirely.
