Connect to the internet - set up web server

[lucad7846]

Hi everyone 

As per post title, I am trying to implement internet connection and set up a web server. 

The diagram I have created works fine in terms of hosts being able to communicate with each other. I have set up the "Perth Router" as the DHCP server configured the trunk links and all. 

Now I would like to connect the network to the internet and set up  the web server. I am a bit lost as to how to achieve this. I have watched some videos on YT but I simply can't get my head around it. 

I have attached my PT file - Password for console and privilege exec mode are cisco and class respectively for all router and switches.  

Any suggestion would be much appreciated 

Please bear with me as I have only starter with networking about a month ago  

Cheers

Luca

Hi

what could be all device password set as cisco is not correct password.

Hi 

I am not an expert, but I don't think the passwords have anything to do with the issue I am having. I need to set up a internet connection and configure the web server.

If someone could have a look at my design and give some tips that would be greatly appreciated.

Hello,

what (if any) instructions are you following ? The router that connects to the Internet needs to have NAT configured. I don't know if this is supposed to be the Perth or the Sidney router ?

Let's say the Perth router is the ISP/Internet facing router; you would need to add the lines marked in bold:

Hi Georg 

Thanks so much for getting back to me. 

To be honest I was trying to follow a couple of tutorials I found on YT but got very confused. 

To answer your question, yes it's the Perth Router that needs to connect to the internet. 

I will try and implement the configuration as per your suggestion. 

One other thing that I am confused with is the actual connection between the router and the ISP. Doesn't this require a static route from the router to the cloud? Or maybe I am really mixing thing up? 

Also I am required to use a variable length subnet between the router and the ISP. 

Please bear with me as I am really new to networking. 

Many thanks in advance

Luca

Hello,

if you need a variable length subnet between the router and the cloud, you could use any /30 address you want, e.g.:

interface GigabitEthernet0/1
--> description WAN to Internet
--> ip address 100.100.100.1 255.255.255.252
--> ip nat outside
duplex auto
speed auto

The static route:

--> ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/1

works, but if you have a fixed IP address, you can also use:

--> ip route 0.0.0.0 0.0.0.0 100.100.100.2

Hi Georg 

Brilliant! Thanks so very much for the info.

As for the static route

The above command is actually - ip route 0.0.0.0 0.0.0.0 100.100.100.2 as you typed it including both addresses? or you meant ip route followed by one of the 2 addresses? Depending on which one I want to use?

Thanks for being so patient! Much appreciated

Hi Georg 

So very sorry if I am bothering you. But one thing is still not clear 100% 

When you say 

--> ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/1

works, but if you have a fixed IP address, you can also use:

--> ip route 0.0.0.0 0.0.0.0 100.100.100.2 

Do I need to enter the command exactly like that ip route 0.0.0.0 0.0.0.0 100.100.100.2?

Or I need to use the ip route command followed by one of the 2 addresses? This is the part that is not clear.

Thanks so much for your patient

Cheers

Hi Again

I have made the required changes as per you suggestion.

Just to clarify is the following the static route "ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/1"? 

Many thanks in advance
