SM Configuration: Bridging, NAT, DMZ, Static IP, QoS

Bridging an SM

Use when the NAT Out Of Resources count is high (1000+), or when a customer needs a direct public IP.

  1. Open the SM → Configuration → NAT
  2. Change NAT Enable/Disable to Disabled. Equipment will reboot.
  3. Navigate to Statistics → Bridging Table. Copy the Physical Address of the device with Interface Name "Eth0".
  4. In Powercode, click More on the customer router → Edit Device
  5. Click Modify MAC Address → enter the customer router's MAC address from the bridging table
  6. Save. Equipment will reboot (may take longer than normal).

Converting an SM Back to NAT'd

  1. Open the SM → Configuration → NAT
  2. Change NAT Enable/Disable to Enabled. Equipment will reboot.
  3. In Powercode, copy the MAC address for the CPE → click More on the customer router → Edit Device
  4. Click Modify MAC Address → enter the SM's MAC address, but change the first octet from 0A to 2A. Example: 0A:00:3E:B3:90:D1 becomes 2A:00:3E:B3:90:D1.
  5. Save. Equipment will reboot.

Configuring DMZ

Use when customers complain of "NAT Type Strict" or similar gaming/firewall issues. This places their router outside the SM's firewall.

  1. Open the CPE → Configuration → NAT
  2. Set Subnet Mask to 255.255.255.252
  3. Set DMZ Enable to Enable
  4. Set DMZ IP Address to 192.168.10.2
  5. Under LAN DHCP Server:
    • DHCP Server Lease Timeout: 1
    • DHCP Start IP: 192.168.10.2
    • Number of IP's to Lease: 1
  6. Save and reboot the CPE. If needed, have customer reboot their router too.

Static IP Setup

Note: This is normally completed by an Engineer. Verify it's in Powercode before giving info to customer. Ping the Gateway in Command Prompt to confirm it's routed.

  1. Go to Inventory Tab → Add Remote Subnet
  2. The Network is 1 below the Gateway (e.g., Gateway 162.210.61.163 → Network 162.210.61.162)
  3. Select Subnet Mask from dropdown (will only be /29 or /30)
  4. Save

Then:

  1. Delete the customer's router from the account
  2. Login to the radio and bridge it
  3. Provide the customer: Usable IP, Subnet Mask, Gateway, Primary and Secondary DNS
  4. Customer must enter all info in their router before they can get online

Quality of Service (QoS)

QoS settings are sent to each SM based on what plan the subscriber is on. Settings live in Configuration → Quality of Service (QoS) on the SM.

The Sustained Downlink/Uplink Data Rates should match the customer's plan speeds.

Pro Tip: When troubleshooting, you can set both Sustained Downlink and Uplink Data Rates to 155,000. This lets the device pull its full throughput and confirms the SM's actual capacity at that location.
