Assign IP's

Unanswered Question
Feb 17th, 2008

I have been assigned the following from my ISP.


WAN: 199.0.161.246 /30 (255.255.255.252)


Your IP Address Subnet Block:

Network: 199.0.169.16 /29

NetMask: 255.255.255.248

Broadcast: 199.0.169.23

Default Route: 199.0.161.245


I have a Cisco 1760 with a 4 port switch. I setup FastEthernet 0/0 as 199.0.161.246. Should I then setup a Vlan as 199.0.169.17 and assign .18 and .19 to my servers?

Make sure to incorporate a default route to 199.0.161.245 (ISP router connected to you) in your configuration.


Other than that, it should work provided the ISP is announcing the 199.0.169.16/29 out to the internet.


The servers .18 and .19 should have a default gateway to .17.

Thanks, that helps.

To set the default route, it this correct?

ip route 0.0.0.0 0.0.0.0. 199.0.161.245

I have completed that. The servers can see each other, but I can not get to the internet. My WAN, fastethernet0/0 is up, but the protocol is down. When I look at ip routes, it says Gateway of last resort not set. Its shows 199.0.169.0/29 is subnetted, 199.0.169.16/29 is directly connected , VLAN1.

Any suggestions?

We need to make sure the interface is up/up before dealing with any ip route issues.


What's the device providing the connection to F0/0?

You need to troubleshoot that connection. Make sure the encapsulation matches (are they using PPPoE?) and the wiring is correct.


The goal is to have the FasEthernet up/up.

I have entered the default route. When I look at routes, it still says Gateway of last resort not set. Is this normal?

Edison Ortiz Mon, 02/18/2008 - 07:37

The next-hop is not available at the moment since the FastEthernet is down. Once the FastEthernet is up/up, the route will be shown.


Wasn't I helpful on my previous post? not sure about the rating of '1'.


There is nothing I can suggest about bringing a LAN interface up/up other than checking wiring issues. Is that simple.

Thanks for you help. I appreciate it. Your advice.


"You need to troubleshoot that connection." That is what I am doing.


"Make sure the encapsulation matches (are they using PPPoE?)" I guess I should have been more specific. It is ethernet to another router.


"The goal is to have the FasEthernet up/up."


Edison Ortiz Mon, 02/18/2008 - 07:51

PPPoE is done over Ethernet and that's the only protocol that I can think of, which would prevent an LAN interface from coming up/up if the wiring is fine.


If it's Ethernet to another router, you need a xover cable.


Good luck with dealing with the Colo tech-support :)
