Don't change any settings on this page.
You had to setup DMZ in Applications & Gaming Tab. Enable it and set there IP address of connected computer (192.168.1.2). This address also will be WAN IP of your Cisco.

This modem can be switched to "Bridged Mode Only", but you need contact your provider and ask: is it possible or not. Modems on both sides should be switched to bridge mode.

Hi Als315,

I have done configuration on Linksay's modem, I have configured device in Bridge mode & LLC  encapsulation, but not getting internet through Cisco 1861...

als315Commented:
Can you show you configuration? Something like this:
Internet provider (IP of Gateway)<---> Linksys (In bridged mode IP should be from unroutable range - 192.168.*.* or 10.*.*.*) <---> Cisco 1861 (WAN IP, LAN IP) <---> Devices (IP range)
You can show only last digits group and mask for external IP addresses.

192.168.8.1 - WAN or LAN IP address?
Normally WAN IP address of Cisco 1861 should be address from your provider, Gateway - IP of provider's router.

Light on modem means only ADSL link is on, but nothing about TCP/IP. Who is your ISP? Have you consulted with them about bridge mode?

It was difficult to find anything helpful on your ISP's site.
Settings for Windows Vista and non optus modems:
http://help.optuszoo.com.au/help/dsl/connected/windows/modemwvista/speedstream_eth#pc_settings
Seems your ISP is using PPPoE
And I think Linksys can't be used in bridge mode with PPPoE Connection.

Hello,

If Linksys can't be used in bridge mode with PPPoE Connection. so which protocol need to be done for fix this issue
0
 
als315Commented:
May be you don't need bridge mode?
You can set Linksys to PPPoE with necessary authorization (as in example before) and  forward all traffic to internal address (WAN Linksys - dynamic IP, LAN - 192.168.1.1; WAN CISCO - 192.168.1.2). You should be able connect to internet

kavinagpurAuthor Commented:
You mean I ned to forward all traffic to internal address  (WAN Linksys - dynamic IP, LAN - 192.168.1.1; WAN CISCO - 192.168.8.1).
Linksys IP:- 192.168.1.1
Cisco       : 192.168.1.1
0
 
als315Commented:
Yes, you can transfer all traffic.
Cisco should have address different from Linksys LAN address (192.168.1.2, for example)
0
 
als315Commented:
Default Gateway for Cisco will be Linksys's LAN address 192.168.1.1. For DNS you can use ISP's DNS or Google (8.8.8.8 and 6.6.6.6)

You had to set IP address of computer to auto. Unplug and plug again LAN cable, check IP address. If it is assigned, open in browser same address as assingned, but with last digit equal to 1.

IT is pppoe connection, which is done by Linksys, you don't have it in cisco. You need it only if Linksys is in bridge mode, but it is impossible

As I have recommended before, connect computer directly to LAN interface of Linksys (set for LAN adapter of computer same settings as Cisco) and check Internet connection

Sorry, I don't understood you.
If from Lap-top all is working, can you try tracert to any outside IP address from computer after Cisco.
I'm not so familar with CISCO IOS.
How you are configuring your Cisco?
With Cisco Router and Security Device Manager or manually?

In Linksys all seems to bo ok (you don't need add routes to 192.168.8.0), but I can't help you with Cisco configuration.
I hope only, IP of interfaces are correct.

I think you should change zone of question to Cisco.
If you will use any of Cisco GUI tools, you can model your configuration.
