help with cisco 887va and vodafone

[skyjames83]

hi all

please forgive my ignorance , i am very very new to cisco and i know nothing about it at all . The reason for this post is would like to use a cisco 887va to replace my vodafone crappy little hub with i use for my house  , i the reason i want to use the cisco is i was given it brand new and was told it was a much better product and wont let me down . After reading many web pages and artivles i know i have made the right choice .does anyone have a working config that works so i have NAT ? i also have a cisco linksys switch which runs all my house like xbox one , ps4 , laptops and other equipment that uses ethernet 

many thanks for reading this and greatly accept any info 

regards

Hi

Before you go about setting all that up , these routers only support max maybe 20 -30mbps throughput , if your line is less than that your ok , usually the get to about to 12-15mb when all service are on

If your VDF line is more than that you may want to think twice or youll loose bandwifdth , most households these days have lot higher bandwifdth than whats available at business level due to cost

If its only 10mb line or something your fine , you need to know exactly what that modem is doing and what type of line you ahve and the passwprd settings for the circuit too , it could be pppoe service whihc will require username and password , then you can check if modem can do bridge mode and tht will allow public interface to be pulled back onto teh Cisco router and then do the NAT on the 887 itself

Heres a good guide you can review of whats involved in teh setup

Not sure about diagrams if search online you may get some
here's a PPPOE configuration full example in this link which would do for you

maybe a video would help youtube is full of them for PPPOE as its quite popular service

thanks

would i just have to copy and apply this config to the 887 and put my username and password in , would that connect me to the interent  ?

[Mark Malone]

YOU NEED TO PUT THE MODEM IN BRIDGE MODE SO THE PUBLIC IP ADDRESS IS ON THE CISCO ROUTER THEN RATHER THAN THE MODEM

[skyjames83]

thanks

i can put the bt openreach modem into bridge mode how would the 887 get the public IPs 

[Mark Malone]

This bit in the config ip adress negotiated  , when bridge mode is enabled the modem will push the ip back , this will allow it to be picked up by the Cisco router and negotiate once the pppoe is correct and it can speak to the BT router upstream

interface Dialer1

description Logical ADSL Interface

ip address negotiated

[skyjames83]

ok great 

in the config that has been posted above could you copy that and put that bit of information in for me please 

many thanks you have been very supportive 

[skyjames83]

which one of these options would i be using ??

[Mark Malone]

If you read through the examples there both nearly identical , one is using vlans the other is using the actual Ethernet port but the important bits are there the PPPOE requirements , I would have a look at the video too as it explains what its doing in it

[skyjames83]

thanks for this config 

were would i put the command for the public IP in this config , also does this also cover the NAT issue for playing xbox and ps4 consoles ?

is there a config that i can just use to just use the 887 as i have a high end network switch and my wifi is delivered by ruckus R510 on a unleashed mode 

any help is greatly welcomed 

[Georg Pauwen]

Hello,

the public IP address would be assigned to the dialer interface:

interface Dialer0
description ADSL WAN
ip address xx.xx.xx.xx 

NAT works for everything and all ports. That said, and I did not follow the entire thread, is your modem in bridge mode ?

The sample configuration automatically assigns IP addresses in the 192.168.1.0/24 range to your LAN hosts. Do you have IP addresses from another range in your LAN ?

[skyjames83]

thanks

OPTION1

i have 2 options , if i can just use the 887 ( brilliant) i just need the complete config so i can just apply it and away we go , i have a cisco linksys srw2024 so would that assign ip address 

OPTION 2 

i can use the openreach modem in bridge mode then connect to the 887 via cat6 all i need is  the config for the 887 to use it this way 

IM NOT SURE WHAT YOU MEAN BY THIS ? Do you have IP addresses from another range in your LAN ?

i am very very VERY new to this , my concern is the rest of the devices that connect to the net
