The LAN Configuration Web pages allow you to configure the following LAN settings:
•LAN IP address and subnet mask;
•LAN broadcast and multicast traffic limitation;
•Rate control;
•DHCP Server settings;
•Port forwarding – to enable access to local ports from an external network.
To open the LAN Configuration pages:
In the vertical menu bar on the left of the Access VoIP Gateway Web page, select LAN.
The LAN Configuration page appears (Figure 6).

ACCESS 211 VOIP GATEWAY (AC-211) USER GUIDE
MN100129 Rev A01

Figure 6: LAN Configuration Page
Configuring LAN Settings
To configure LAN settings, broadcast and multicast traffic limits and/or rate control, proceed
as follows:
1. In the LAN Configuration page, enter the LAN IP address and subnet mask.
2. Optionally, set the broadcast and multicast limits in the appropriate fields.
3. Select one of the following Rate Control options:
•Disable Rate Limits (this is the default setting)
OR
•Dynamic Rate Limits
OR
•Fixed Rate Limits
With the Rate control feature you can limit the bandwidth allocated to the device(s) connected
to the LAN port. This is especially important for broadband users where the upload link to the

ACCESS 211 VOIP GATEWAY (AC-211) USER GUIDE
MN100129 Rev A01
18
ISP is considerably lower than the download link from the ISP. Setting the Rate control
parameters will insure that even while running heavy bandwidth applications on the devices
connected to LAN port the voice quality is preserved.
Select Fixed Rate Limits to limit the bandwidth received from the LAN to the value of the
LAN Rate Limit that is specified in the textbox (in Kbps). If you change this value, the actual
rate limit will be rounded to the nearest multiple of 32 Kbps.
If you want to select the Dynamic Rate Limit option you must first set the User Upload Rate
parameter to the value of the user’s available upload bandwidth on the WAN connection. The
Access gateway will dynamically reserve bandwidth for the active calls and limit the
bandwidth for the LAN device to the remaining available bandwidth. By default the User
Upload Rate is set to 32 Kbps. If you change this value, the actual upload rate will be rounded
to the nearest multiple of 32 Kbps. You can view the actual bandwidth allocated to the LAN
device in the Current LAN Rate Limit parameter.
4 Click Save LAN Settings.
DHCP Server Configuration
To use DHCP Server for assigning IP addresses and subnet masks automatically to
devices connected to the LAN port, proceed as follows:
1. In the horizontal menu bar of the LAN page, select DHCP.
The DHCP Server Configuration page appears (Figure 7).
Figure 7: DHCP Server Configuration Page

ACCESS 211 VOIP GATEWAY (AC-211) USER GUIDE
MN100129 Rev A01
19
2. To enable the DHCP Server, select the Server Settings Enabled option.
3. Fill in the following fields:
•Client IP Address range – up to 10 IP addresses are allowed. To change the LAN
IP, see Configuring LAN Settings on page 17.
•Domain Name – optionally enter the domain name for the local LAN.
•DNS Server 1 and 2 – if left blank, the DNS Server IP addresses will be acquired
from the WAN connection. If you want to use different DNS Server addresses,
enter their IPs.
•You can define LAN devices statically. The devices can be defined by Host
name or by MAC address:
oIdentity Using – Select the type of identifier, Host name or MAC,
you wish to use in the next field.
oHost Identifier – Enter the appropriate value (Host name or MAC).
oInternal address – static IP of the local host.
4. To view the DHCP Client table (Figure 8), click on View DHCP Table.

Port Forwarding
Port forwarding associates local port ranges to local P addresses in order to enable external network
users to access local devices, without the need for the local servers to first access the global
network.
To configure port forwarding:
1. In the horizontal menu bar of the LAN page, select Port Forwarding.
The Port Forwarding Configuration page appears (Figure 9).
