Changing Ipv6 Firewall Settings - Linksys WRT 1900AC User Manual

VPN Passthrough:
• IPSec Passthrough — IPSec (Internet Protocol Security) is a suite of protocols
used to implement secure exchange of packets at the IP layer. The VPN clients
on the local network can establish an IPSec VPN tunnel through the router. This
option is enabled by default.
• PPTP Passthrough — PPTP (Point-to-Point Tunneling Protocol) allows the PPP
(Point-to-Point Protocol) to be tunneled through an IP network. The VPN clients
on the local network can establish a PPTP VPN tunnel through the router. This
option is enabled by default.
• L2TP Passthrough — L2TP (Layer 2 Tunneling Protocol) enables point-to-point
sessions using the Internet on the Layer 2 level. The VPN clients on the local
network can establish an L2TP VPN tunnel through the router. This option is
enabled by default.
Internet filters:
Filter anonymous Internet requests — This filter blocks Internet requests from
unknown sources such as ping requests. This option is enabled by default.
• Filter multicast — Multicasting allows a single transmission to simultaneously
reach specific recipients within your local network. Select this option to block
multicasting. This option is disabled by default.
• Filter Internet NAT redirection — This filter prevents a local computer from
using a URL or Internet IP address to access the local server. Select this option
to enable the filter. This option is disabled by default. On some router models, this
setting applies to IPv4 Internet only.
• Filter ident (Port 133) — This filter prevents port 133 from being scanned by
devices from the Internet. This option is enabled by default.

CHANGING IPV6 FIREWALL SETTINGS

On some router models, the IPv6 firewall lets you customize IPv6 port services
for applications. When users send these types of requests to your network via the
Internet, the router will allow those requests to the appropriate computers.
Note:
To use your router's IPv6 Internet connection settings, IPv6 service from your
ISP (Internet service provider) is required. For more information on this service,
ask your ISP.
