Network Configuration Oddities
I have the following network setup:
* Actiontec M1000 DSL Modem/Router - configured as the network gateway:
- ISP Protocol: PPPoE
- Modem IP Address: 192.168.0.1
- Subnet Mask: 255.255.255.0
- DHCP Server: On
- DHCP Start: 192.168.0.3
- DHCP End: 192.168.0.254
- DHCP Subnet Mask: 255.255.255.0
- Dynamic DNS: On
- NAT: On
* Linksys WRT54G2 Wireless Router - configured as an access point:
- Internet Connection Type: Automatic Configuration - DHCP
- Local IP Address: 192.168.0.2
- Local Subnet Mask: 255.255.255.0
- DHCP Server: Off
- Operating Mode: Router (not Gateway)
- RIP: Disabled
The M1000 is connected to the WRT54G2 via CAT5 cable between the Ethernet ports on each device (not the WRT54G2 WAN port). The NIC on my Windows 7 PC is connected to the WRT54G2 via CAT5 cable between the Ethernet ports on each device.
This setup works (connects to internet, connects to wireless devices, etc.) but there are some oddities that I do not understand:
1. The Network Map (Control Panel -> Network and Sharing Center -> See Full Map) shows a device chain of PC -> WRT54G2 -> Gateway -> Internet (which is correct). However, when I right-click on the Gateway, it shows two devices: Actiontec M1000 and Actiontec TR64 M1000. This makes absolutely no sense to me.
2. The MAC Addresses reported by the Network Map for the WRT54G2 and the Gateway are off by one from the values reported by the device Management URL (e.g. WRT54G2 - Network Map says 00:23:69:7e:ac:4b; Management URL says 00:23:69:7e:ac:4c). Weird.
3. Running 'ipconfig /all' reports the primary DNS Server is 192.168.0.1 (the gateway) and the secondary DNS Server as one of the ISP's DNS servers. When I run an 'nslookup' on a domain name, I always get two 'DNS request timed out' errors (presumably from the gateway) before it returns the addresses (presumably from the ISP's DNS server). I don't understand why the gateway is being set as a DNS server rather than the ISP's DNS servers which are normally set via DHCP.
Does anyone have a clue what would cause these oddities?
Thanks
