Start at Part 1

Configuring the Interfaces

First step is to configure the interfaces. My external interface is rl0 (”Realtek 8139″ - you can see dmesg below), my internal wired interface is xl0 (”3Com 3c905B 100Base-TX”), and my wireless interface is rum0 (”Ralink 802.11 bg WLAN”).

As I stated in Part 1 the external interface (rl0) will be a dhcp client to my cable ISP. To configure this, I created /etc/hostname.rl0 with the following information:

dhcp NONE NONE description "Global Uplink"

ifconfig rl0 looks like this:

rl0: flags=8843 mtu 1500
lladdr 00:0d:87:07:07:56
description: Global Uplink
groups: egress
media: Ethernet autoselect (100baseTX full-duplex)
status: active
inet6 fe80::20d:87ff:fe07:756%rl0 prefixlen 64 scopeid 0x2
inet  netmask 0xfffffe00 broadcast 255.255.255.255

Next the internal wired interface (xl0); will be statically configured with the address 192.168.0.1 with a 24 bit subnet mask, later this interface while be advertising DHCP service for the wired local network. I created /etc/hostname.xl0 like this:

inet 192.168.0.1 255.255.255.0 192.168.0.255 description "Local Wired"

ifconfig xl0:

xl0: flags=8843 mtu 1500
lladdr 00:10:5a:0e:da:9a
description: Local Wired
media: Ethernet autoselect (100baseTX full-duplex)
status: active
inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
inet6 fe80::210:5aff:fe0e:da9a%xl0 prefixlen 64 scopeid 0x1

And lastly the wireless interface (rum0). This interface is being set up as a wireless access point (”hostap”) configured as follows:

• Will be set to only support 802.11B for the time being
• Utilizing channel 6
• Use a hex WEP key
• Configured as 192.168.1.1 with a 24 bit netmask
• And later will be advertising DHCP for the local wireless network

My /etc/hostname.rum0 looks like this:

up mediaopt hostap mode 11b chan 6 nwid Puffy nwkey 0x
inet 192.168.1.1

ifconfig rum0:

rum0: flags=8843 mtu 1500
lladdr 00:1c:f0:90:82:22
groups: wlan
media: IEEE802.11 autoselect mode 11b hostap
status: active
ieee80211: nwid Puffy chan 6 bssid 00:1c:f0:90:82:22 nwkey 0x 100dBm
inet6 fe80::21c:f0ff:fe90:8222%rum0 prefixlen 64 scopeid 0x5
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
