Cisco 1800 configuration

[simpyhemant]

Hi All,

I have adsl connection at home and from adsl connection one port is connected to my cisco 1812 router.

I want to create LAN connection on this router to connect four laptops through ethernet.

Port details are as below :

one console port
one AXE port
ONE ISDN port
six ethernet ports & 2 more separate ethernet ports.

Now, I want to ping the laptops from each other and everbody should be able to browse Internet.

My default gateway for my ADSL modem is 192.168.1.1 255.255.255.0

I want two VLANs.

I would highly appreciate if any one can tell me the range of IP address with examples so that I can use in my router .

I am very confused assiging IP address to port.


My understanding is we assgin two address to router one Publick and private.

A public address should assgin to defult vlan1 .

I am really confused please help my I have exam next month and I am doing self study.

Please let me know if you require any more details

This may be a bit late, but the router is capable of using DHCP. Set up a DHCP Pool using the same ip subnet range you posted. This range you posted is a private range. You would use an exclude command in the config set up to make sure you have some reserved IP's for static use, if needed.

conf t
service dhcp
ip dhcp pool 192.168.1.0/24
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 192.168.1.5 192.168.1.6 <the DNS is provided by the ISP, ask the ISP for the IP's to use>
exit
ip dhcp excluded-address 192.168.1.1 192.168.1.100 <this will make sure DHCP starts at .101 as the first usable. This will help if you need to look at the arp table to help troubleshoot, you can really use whatever block you want.
