Setting up T1 Router....can not see router

[Time2Kill]

I just got my T1 line activated this morning. I'm using a Tasman 1001 T1 router. Everything has been verified that it is working, although I can not gain access to the internet. I've tried plugging a PC straight into the T1 router, connecting the router to my network, and plugging it into the WAN port on my Linksys WRT54G and I can not see the damn thing or gain access to it. I've tried setting the WRT54G to DHCP-Automatic mode and it does not pick it up, and also tried using Static IP, but everytime I put in the IP of the router, it says invalid IP and clears it out.

I also have no idea how to telnet into the T1 router, it came with a serial adaptor and cable to plug into the router, but once I connect it to the PC, I have no idea how to get to the CLI of the router. I wanted to check to make sure the router was setup correctly from the T1 carrier.

My network is currently setup and completely controlled by the DHCP server on the WRT54G on the addresses 192.168.1.100 to 192.168.1.150.

I have the following IP addresses provided by my T1 carrier:

Carrier serial IP address: 67.98.108.97
Carrier serial IP subnet mask: 255.255.255.252
Customer serial IP address: 67.98.108.98
Customer serial IP subnet mask: 255.255.255.252
Customer Router Ethernet IP address: 216.142.208.129
Customer Router Ethernet subnet mask: 255.255.255.240
Primary DNS Resolver: 216.140.16.254
Secondary DNS Resolver: 216.140.17.254

I really have no idea what I'm doing and not getting much help from my T1 carrier either so any help from you guys would be greatly appreciated. I am a bit confused by the Router IP Address above as I thought most router addresses ended in .1 or .254.

I can ping 67.98.108.98 and get a response, so I know the router is working and has a physical connetion to the internet.

the router will need a default route pointing to 67.98.108.98

from there the "customer ethernet IP address" is the addressing for your LAN

I'm not familiar with that router otherwise you'd be all set in just a few minutes.

When you say router, I'm assuming you mean the Linksys WRT54G.

If I setup a manual route on my router, it asks for Destination LAN IP, which I assume would be the ip of 67.98.108.98, but it also asks for subnetmask and gateway. Should I use 255.255.255.252 as the mask and leave the gateway blank? What do you mean when you say its the 'addressing for your LAN'

When I say router, I mean the Tasman T1 router, unless your provider already set that up for you.

Is your router getting a address from DHCP somewhere on the wan port? you'll need the wan port of the linksys attached to the ethernet port of the Tasman

The router should of been setup by the provider. I can ping the router over the internet using my IP address of 67.98.108.98 and the provider has verified that they can also see the router on their end.

I've been connecting the T1 router to the Wan port on the linksys via a crossover cable. I've also tried a straigh through cable with no luck. Once its connected to the WAN port, I can not get the linksys to set up automatically. Ive also tried setting it up manually with no luck.

 

[spidey07]

the linksys WAN port is not getting an IP? No biggie, you'll just have to specify one.
Customer Router Ethernet IP address: 216.142.208.129
Customer Router Ethernet subnet mask: 255.255.255.240

give the WAN port 216.142.208.130 using a mask of 255.255.255.240
then you may have to add a default gateway of 216.142.208.129 on the linksys as well. this should be in the IP setup of the wan port.

should be good to go from there.

This is how I tried setting it up on the linksys router: http://www.eadperformance.com/t1/basicsetup.jpg and the routing: http://www.eadperformance.com/t1/advancedrouting.jpg

This is how it works with my satelite: http://www.eadperformance.com/t1/basicsat.jpg and http://www.eadperformance.com/t1/advancedsat.jpg

spidey, thanks for the help, that worked!!!

Spidey,
Would you mind telling me what each of those IP addresses is? I've only used T1 once before. A UseNet search didn't find the answer for me:

a) Carrier serial IP address.
b) Customer serial IP address.
c) Customer Router IP address.

Based upon what you said, the "Customer Router IP address" must be the inside IP of the Tasman router.

And, I guess, the "Customer Serial IP address" must be the outside IP (WAN port) of the Tasman router?

And the "Carrier Serial IP address" is the ISP's Demarcation Point?

Thanks for any hints,

Lots of times that is how a point-2-point link is described, no matter if it is a T1 or a T3 or a OC3.

There are only a few things important from a customers perspective (taking out any active exchange of routing...BGP)

1) what is my address range and mask
2) what is my next hop

Here's is what any carrier/customer point to point link looks like...
Customer router-----circuit----provider router
----------------------------------------------------------------------
"Carrier serial IP address: 67.98.108.97....................this is the ip address of the provider router interface
Carrier serial IP subnet mask: 255.255.255.252 ................this is the mask of the provider router interface
Customer serial IP address: 67.98.108.98 .....................this is the ip address of the customer's serial/wan interface
Customer serial IP subnet mask: 255.255.255.252 .................this is the mask of the custoer's serial/wan interface
Customer Router Ethernet IP address: 216.142.208.129 ..................this is the ip address of the customer router (what the customer should direct any traffic to)
Customer Router Ethernet subnet mask: 255.255.255.240 ................this is the mask of the customer router. Remember routers are the ones that dictate and indeed actually ADDRESS a network
Primary DNS Resolver: 216.140.16.254
Secondary DNS Resolver: 216.140.17.254
"

Hope that helps. It helps to quickly dispose of the concept of inside and outside and think purely in terms of networks and routing.
