OfficeConnect VPN Firewall User’s Manual Chapter 5. Configuring LAN Settings

When performing DNS relay, the OfficeConnect Gigabit VPN Firewall must

maintain the IP addresses of the DNS servers it contacts. It can learn these

addresses in either or both of the following ways:

 Learned through PPPoE or Dynamic IP Connection: If the

OfficeConnect Gigabit VPN Firewall uses a PPPoE (see section 8.2.2

Configuring PPPoE for WAN) or Dynamic IP (see section 8.4.2 Configuring

Dynamic IP for WAN) connection to the ISP, the primary and secondary

DNS addresses can be learned via the PPPoE protocol. Using this option

provides the advantage that you will not need to reconfigure the PCs or the

OfficeConnect Gigabit VPN Firewall if the ISP changes their DNS

addresses.

 Configured on the OfficeConnect Gigabit VPN Firewall: You can also

specify the ISP's DNS addresses in the WAN Configuration page as

shown in

Follow these steps to configure DNS relay:

1. Enter LAN IP in the DNS Server IP Address field in DHCP

configuration page as shown in Figure 5.3.

2. Configure the LAN PCs to use the IP addresses assigned by the

DHCP server on the OfficeConnect Gigabit VPN Firewall, or enter

the OfficeConnect Gigabit VPN Firewall's LAN IP address as their

DNS server address manually for each PC on your LAN.

Note

DNS addresses that are assigned to LAN PCs prior to enabling

DNS relay will remain in effect until the PC is rebooted. DNS relay

will only take effect when a PC's DNS address is the LAN IP

address.

Similarly, if after enabling DNS relay, you specify a DNS address

(other than the LAN IP address) in a DHCP pool or statically on a

PC, then that address will be used instead of the DNS relay

address.

5.5 Configuring the Port Settings

This page allows you to enable/disable a specific port, change the port speed or

enable/disable DMZ ports. Follow these steps to configure the port settings:
