Select this check box to have the content filter apply to traffic that the
ZyWALL sends out through a VPN tunnel or receives through a VPN tunnel.
The ZyWALL applies the content filter to the traffic before encrypting it or
after decrypting it.
Note: The ZyWALL can apply content filtering on the
traffic going to or from the ZyWALL’s VPN tunnels.
It does not apply to other VPN traffic for which the
ZyWALL is not one of the gateways (VPN pass-
through traffic).

containing a restricted feature, that part of the web page will appear blank or
