IP Configuration settings for T1 line on my Router
Posted on 2010-08-22
I have a new T1 line from Speakeasy installed and ready to go, but I don't know how to setup my TP-LINK TL-R480T+ router for the T1 I line. I'm having trouble interpreting the IP configuration details that speakeasy gave to me. I'm not sure if it's "safe" to post specific details about my IP configuration, so I'm censoring out those details, but will provide them if necessary/
Here's what speakeasy told me to use:
Your WAN IP is: aa.aa.aa.aaa
Your WAN Subnet Mask is: 255.255.255.0
Your LAN IP is: bb.b.bbb.b
Your LAN Subnet Mask is: 255.255.255.240
The broadcast address for your /28 block is bb.b.bbb.31.
Your last usable IP address will be the IP before the Broadcast address.
But on my router, I only have the ability to enter settings for:
And I'm not sure which settings to use. I'm especially confused as to the difference between WAN ip and LAN ip -- I'm assuming WAN ip is what "the rest of the internet" sees as my IP address, so then what's the point of the LAN ip for my internal network? I'm already using DHCP so maybe the LAN ips are unnecessary for my network... if someone could please explain that I'd appreciate it.
Basically what I need right now is correct router settings (for the above fields), and if somebody's feeling especially generous with their time, a clarification on what the difference between WAN / LAN ips are and an example of usage.
