CPE Setup

CPE Setup w/NAT and DHCP Auto-Auth

This is my standard CPE setup. We provide a public IP address to the CPE's wpci interface and NAT a private subnet to the customer's LAN.

Interface Configuration

• Setup the wireless interface.
  • interface > wpci1 > ip assignments. Assign your static IP assignments here.
  • interface > wpci1 > wireless configuration > config current card.
    • ENABLED = Turn your wireless card on or off, select for on.
    • ESSID = your essid
    • Channel = auto
    • Transmit Rate = (<-75 lock on 11)
    • Link Distance = (actual +2 miles)
    • Country Code = US
    • TX Power Overide = Only set as high as you need it. Not above 20.
    • Cloaking = 1x/2x/4x - 20/10/5MHz channel sizes. AP and Client must match.
    • Antenna Select = Antenna A/B/Diversity - MAIN/AUX/BOTH Radio Antenna Ports.
    • HIDE SSID = enable to hide your ESSID from AP scanners.
    • InterBSS Relay = enable for client to client communication. Not a good idea.
    • Outdoor Only = Channel Display Column will only show outdoor channels.
    • Short Preamble = Enable
    • Super A/G = Enable
    • AP Power Savings = Enable
    • Network Type = Station
    • Operating Mode = 802.11a/b/g, 802.11b/g mixed or Turbo (select your operating mode)
  • WEP Setup
    • WEP Mode = Disabled/40/104/128bit
    • Passphrase = To generate a wep key using a passphrase.
    • WEP Key 1/2/3/4 = WEP Keys must match and they must match the same Key slot as the AP.
    • Selct either "Open" or "Shared Key"
  • interface > interface feature > "select" enable DHCP client. Your CPE will dynamicly obtain IP address from your AP.

• Setup the ethernet interface
  • interfaces > ether1 >
  • ip assingments = 192.168.200.1/24
  • ethernet link settings = auto/10/100mbps + full duplex on/off
  • dhcp auto-auth configurations > configurations =
    • Gateway: 192.168.200.1
    • Subnet Mask: 255.255.255.0
    • Pri. DNS: 1.2.3.4
    • Sec. DNS: 1.2.3.5
    • Lease: 1700
    • USE Radius = on or off
    • create hotspot session = on or off
    • IP Range = 192.168.200.100 - 254
  • interface features > enable dhcp auto-auth

Routing

• Routing > dynamic routing (rip, ospf & mesh) = enable rip
• routing > static and default routes = remove default routes

dns server list

• advanced > dns server list...
  • hostname = jdoe
  • domain = wisp.domain.net
  • name server 1 = 1.2.3.4
  • name server 2 = 1.2.3.5
  • name server 3 = 1.2.3.6

ntp and timezone

• advanced > ntp and timezone setup...
  • offset = enter your offset here (example -06:00)
  • NTP Server = ntp.server.net

qshape

• advanced > scripts > class based queing...

example

qshape user 100 bw 1536k 512k 192.168.200.0/24 on ether1

see qshape article for more details

nat and static nat

• advanced > scripts > nat and static nat...

example

masq from 192.168.200.0/24 to dev wpci1

file > activate changes > yes

That's it.

Once you have a working config you like, create a backup using starutil and pre-load your CPEs during assembly.

Comments welcome.
