General Setup
Enable Content Filter Select this check box to enable the content filter. Content filtering works on
HTTP traffic that is using TCP ports 80, 119, 3128 or 8080.
Enable Content Filter for
VPN traffic 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).
