Accept large incoming…

Some on-line games (for example: Half Life) will use lots

of fragmented UDP packets to transfer game data.

Instinctively as a secure firewall, Vigor router will reject

these fragmented packets to prevent attack unless you

enable “

Accept large incoming fragmented UDP or

ICMP Packets

”. By checking this box, you can play these

kinds of on-line games. If security concern is in higher

priority, you cannot enable “

Accept large incoming

fragmented UDP or ICMP Packets

”.

Enable Strict Security

Firewall

For the sake of security, the router will execute strict

security checking for data transmission.

Such feature is enabled in default. All the packets, while

transmitting through Vigor router, will be filtered by

firewall. If the firewall system (e.g., content filter server)

does not make any response (pass or block) for these

packets, then the router’s firewall will block the packets

directly.

Block routing packet

from WAN

Usually, IPv6 network sessions/traffic from WAN to LAN

will be accepted by IPv6 firewall in default.

IPv6

- To prevent remote client accessing into the PCs on

LAN, check the box to make the packets (routed from WAN

to LAN) via IPv6 being blocked by such router. It is

effective only for the packets routed but not for packets

translated by NAT.

IPv4

- To prevent remote client accessing into the PCs on

LAN, check the box to make the incoming packets via IPv4

being blocked by such router. It is effective only for the

packets routed but not for packets translated by NAT.

the dialog box.

Window size

– It determines the size of TCP protocol

(0~65535). The more the value is, the better the

performance will be. However, if the network is not stable,

small value will be proper.

Session timeout

– Setting timeout for sessions can make

the best utilization of network resources.
