So we have to change use the IPv6 address to establish an VPN tunnel between the USG. 4.2 Configuration Guide IPv4 Network Conditions: USG-40W with static WAN: - WAN IP: Local subnet: 24 17.

Application Notes.

Unified Security Gateway.

Version 4.10 Edition 1, 052014.

With an IPv6 feature enabled on the USG, it can assign an IPv6 address to clients and pass IPv6 traffic through IPv4 environment to access a remote IPv6 network.

Configuration Guide Network conditions: USG: WAN1: (Static PPPoE v4) Or WAN1: (Static) Goal to achieve: A USG will assign an IPv6 IP addresses to the clients, which are behind it, and the clients can access a remote IPv6 network by using the USG 6to4 tunnel.

USG configuration Step 1: Configuration System IPv6 Click Enable IPv6 4.

Fill-in 2002:3b7c:a396::1128 in the prefix table as the LAN interface IPv6 address.

Check the IPv6 Router Advertisement Setting box and add the prefix in the Advertised Prefix Table.

Step 4: Enable 6 to 4 tunnel.

Since WAN1 ISP is also the company s VoIP provider, the network administrator wants VoIP traffic primarily sent out over WAN1.

In case WAN1 is down, the VoIP traffic can still go out over WAN2 PPPoE connection.

In case WAN2 PPPoE is down, LAN users can still surf Internet over WAN1.

For all other types of traffic, administrator needs the two WAN connections to share the outbound traffic load, performing load balancing.

Configuration Guide Goals to achieve: 1) VoIP traffic goes out primarily through WAN1.

In case WAN2 PPPoE is down, it will go out via WAN1.

All other traffic goes out via WAN trunk performing Load Balancing with Least 8.

Configure a PPPoE account on WAN2 interface.

Go to CONFIGURATION Object ISP Account, add a PPPoE account: (2) Go to CONFIGURATION Network Interface PPP, add a new PPP interface, which is based on WAN 2 interface: 9 Object ISP Account, add a PPPoE account: (2) Go titleto CONFIGURATION Network Interface PPP, add a new PPP interface, which.

Select SYSTEMDEFAULTWANTRUNK in Default Trunk Selection.

Network Interface Trunk.

To give an example, the company may have an internal FTP server, which needs to be accessible from the Internet as well.

To fulfill this requirement, the user can configure a NAT mapping rule to forward the traffic from the Internet side to intranet side.

Configuration Guide Goal to achieve: User Tom can access the Internet FTP server by accessing the Internet-facing the WAN IP address.

Network Conditions: USG-50: - WAN IP: FTP server IP: Configuration Step 1.

Go to CONFIGURATION Network NAT to open the configuration screen.

Click on the Add button to create a mapping rule.

Step 3. In this page, the user needs to configure: - Rule s name - Select Virtual Server type to let USG-50 do packet forwarding - Fill-in the Original IP (WAN IP) address - Fill-in the Mapped IP (Internal FTP server IP) address - Select the service to be mapped (FTP); the ports will be selected automatically Step 4.

Go to CONFIGURATION Security Policy Policy Control to open the firewall configuration screen.

Here assume the user already assigned the WAN interface to WAN zone and LAN interface to LAN1 zone.

Step 5. Click on the Add button to create a firewall rule to enable the FTP service to pass from WAN to LAN1.

Security Policy Policy Control to open the firewall configuration screen.

Click on Create new Object for this function.

Step 7. Configure the rule to: - Allow access from WAN to LAN1 - Source IP address is not specific - Destination IP address is the FTP server s address - Select FTP service (with port 2021) to be enabled - Select the allow action for matched packets 15.

IPv6 (with IKEv2 only) ISP has changed the environment to IPv6.

So we have to change use the IPv6 address to establish an VPN tunnel between the USG.
