FIRMWARE VERSION 1.0.9.1 HT503 USER MANUAL Page 32 of 59
Range: 0 - 3600
NAT UDP Timeout
NAT TCP idle timeout in seconds. Connection will be closed after preconfigured,
timeout if not refreshed.
Range: 0 – 3600, default is 300
Uplink Bandwidth
The maximum uplink bandwidth permitted by the device. This function is disabled by
default. The total bandwidth can be set as: 128K, 256K, 512K, 1M, 2M, 3M, 4M, 5M,
10M or 15M. The primary function of this setting is to limit the uplink bandwidth for the
device internal system, signaling and NATed traffic. Example: if 512k is configured,
there will be at least 512kbps limited for internal system, signaling and NATed traffic.
Voice or RTP stream will never be limited. See figure 3.
Downlink Bandwidth
The maximum downlink bandwidth permitted by the device. This function is disabled
by default. The total bandwidth can be set as: 128K, 256K, 512K, 1M, 2M, 3M, 4M, 5M,
10M or 15M. The primary function of this setting is to limit the download bandwidth for
the device internal system, signaling and NATed traffic. Example: if 128 is configured,
there will be at least 128kbps limited for internal system, signaling and NATed traffic.
Voice or RTP stream will never be limited. See figure 3.
Enable UPnP
When set to “Yes”, the HT503 acts as an UPnP gateway for your UPnP enabled
applications. UPnP = “Universal Plug and Play”
Reply to ICMP on WAN
Port
When set to “Yes”, the HT503 responds to the PING command from other computers,
but is also made vulnerable to DOS attacks. Default is No.
WAN Side HTTP/Telnet
Access
When set to “Yes”, the user can access the web configuration pages through the WAN
port, instead of through the PC port. Warning: this configuration is less secure than the
default option. Default is No.
Cloned WAN MAC
Address
This allows the user to change/set a specific MAC address on the WAN interface.
Note: Set in Hex format
LAN DHCP Base IP
Base IP for the LAN port, which functions as default gateway for its LAN. Default value
is 192.168.2.1
Note: When the device detects WAN IP is conflicting with LAN IP, the LAN base IP
address will be changed based on the network mask -- the effective subnet will be
increased by 1. For example; 192.168.2.1 will be changed to 192.168.3.1 if net mask is
255.255.255.0. Then the device will reboot
LAN DHCP Start IP
Default is 100
LAN DHCP End IP
Default is 199
LAN Subnet Mask
Sets the LAN subnet mask. Default value is 255.255.255.0
DHCP IP Lease Time
The length of time the IP address is assigned to the LAN clients. Value is set in units of
hours. Default value is 120 hrs (5 days).
DMZ IP:
This function forwards all WAN IP traffic to a specific IP address if no matching port is
used by HT503 or in the defined port forwarding.
