Configure 1800 Router with ethernet connection

We no longer will be using our T1 connection we now have a dedicated lan connecting to the web. I am new to Cisco routers. How do i configure this Router with my settings.

Internet Provider gave me the following info and I am not sure how i can configure it. So i am a bit confused.

Example...... External IP Address 10.1.111.34 Subnet 255.255.255.252 Gateway 10.1.111.33 DNS 127.0.0.1

Internal IP Address 10.1.55.161 Subnet 255.255.255.224

Thanks

configuration terminal interface fastethernet (example, 1/0, you can get this from show ip interface brief) ip address 10.1.111.34 255.255.255.252 description External no shut ! interface fastethernet ip address 10.1.55.161 255.255.255.224 description internal no shut !

Your clients will need to be configured with the gateway, and your default route (presuming this network does not have any other segments that need to exchange routes, is:

ip aroute 0.0.0.0 0.0.0.0 10.1.111.33

Oops - ip route (not ip aroute)

My Provider did not give me all the information and now i am confused. This is what they sent me today.

Example: Serial Block 10.1.11132 /30 TelCove Serial: 10.1.111..33 Customer Prem Serial: 10.1.111.34 Subnet Mask: 255.255.255.252

IP Address Block: 10.1.55.160 /27 Subnet Mask: 255.255.255.224 Network IP Address: 10.1.55.160 Broadcast IP Address: 10.1.55.191

Thanks so much.

Which bit of that confuses you? There is a /30 WAN between the providers core router and the serial interface of your router. Your side is

10.1.111.34 and the providers interface (your default gateway) is 10.1.111.33.

The other address block is what has been assigned to you for your LAN.

I configured the router with the above instructions and i am unable to connect to the internet. I also used the web interface to test the wan connection and it errors out with user defined route.

If you are completely brand new to Cisco then you are going to have to do some research and learning in order to gain the knowledge of how they work. Having your name set to "Ciscohater" wont do you much good on a Cisco forum either.

Cisco equipment is not just a drop in replacement for cheap netgear/linksys/dlink kit. It is complex equipment that needs to be properly configured.

The 1800 series come with the SDM which is a software based configurator using wizards etc. to configure the device. Personally I do not like this and would rather configure it from the CLI. But if you do not have the time to learn the CLI then I would advise that you use the SDM to restore the box to factory defaults and then go through the various wizards on the SDM for setting up the device.

Can you ping 10.1.111.33

Network 10.x.x.x is not a routable address with respect to reaching Internet. Does your ISP provide Network Address Translation (NAT) as part of its service ?

Able reading up on some Cisco stuff i ran the following commands and I was able to connect but the problem is my connection is very slow. I have a 10 meg line but I am only getting 786 speed.

Ip address's are examples.

Router>

Router>enable Router#show running-config Router#configure terminal Router(config)#ip routing Router(config)#config-register 0x2102 interface fastethernet0/0 ip address 10.1.111.34 255.255.255.252 description External no shutdown exit

interface fastethernet0/1 ip address 10.1.55.161 255.255.255.224 description internal no shutdown

Router(config)#ip route 0.0.0.0 0.0.0.0 10.1.111.33 Router(config)#end Router#copy running-config startup-config

  1. Check for errors on the external fastEthernet interface - show interface fa 0/0

  1. Call your ISP and report problem

We had a server setup to run with the ip seetings for testing and worked fine. But we did set the network connections for 10 meg speed not auto. Is there a setting for that is cisco.

If the question is how to configure the router FastEthernet interface for a fixed speed, the interface commands are

int fa 0/0 speed xx duplex < half or full>

Make sure you do not have a duplex mismatch by doing a show interface and checking for error ( runts, crc errors, etc)

Ok so i switched the interfaces to 10 meg / full duplex. I am getting much better speed right now but still not the whole speed. I get about

7900k via the Cisco and 7400 using a server directly connected. I have included the int fa log.

the fa 0/0 is running error free

BTW you can clear the interface counters using the enable mode command " clear counters

Also you change change the interval for the interface traffic avergae to 30 seconds

config t int fa 0/0 load-interval 30 end

Here is the internal connection. It shows show errors.

FYI I have a few people using the DHCP option of this and they are VPNing into a client site and get kicked off every 10 mins.

Thanks for your help. At least I am learning a little bit in the process.

I set those users who are testing the VPN connection to use dhcp from the router.

clear counters

monitor for errors on inside fa interface

If errors persist replace cabling to router - make sure cable is Cat5E or better

I replaced all the cabling and the connection is still slow.

Any idea.

Given that you have eliminated all the interface error issues, then you need to define what you mean by slow.

You will not for a single TCP connection be able to get 10 Megs given that in fact that is what the ISP is delivering to you.

If you search this newsgroup for TCP performance articles you will have tons of hits.

What type of test are you performing to make the throughput performance assessment ?

Things like end system TCP windows size have a big impact on TCP performance for example.

Anotehr big factor is network latency, etc, etc.
