Question

Router configuration

Asked by: dimitry

I have Cisco Wireless Router 871W. I want to configure it in next way:
WAN - receives IP from  DHCP.
LAN - all 4 ports - DHCP from range 192.168.239.200 - 192.168.239.220
Local router IP: 192.168.239.1
WiFi gets IP from same range 192.168.239.200 - 192.168.239.220 or other (not important)
And I want to be able to access WAN from LAN...
Most of the things I did, but routing is not working...
Thanks,
Dmitry

When you run IPCONFIG from a cmd window on the LAN machines do the adapters getting a 192.168.239.2xx address from the router's DHCP server also show 192.168.239.1 as their default gateway?

 

by: dimitryPosted on 2008-02-01 at 23:04:04ID: 20803534

Darr247, yes, default gateway is set properly.

to naughton,
No I didn't touch NAT. But why should I change it ? I didn't want to access internal LAN from outside.
Or in cisco routers you need to set up NAT to go outside as well ?

 

by: naughtonPosted on 2008-02-04 at 12:57:49ID: 20817894

the error is in your NAT configuration.  you need to specify the inside and outside interfaces so that the traffic can eiother be pat's or nat'd depending on you peticular configiguration.  the logic is that you have a single outside ip, and you have 20 ip's using it.

 

by: dimitryPosted on 2008-02-04 at 17:21:20ID: 20819886

naughton, you are probably right. But I need more detailed explanation how to set this NAT... :)

 

by: naughtonPosted on 2008-02-04 at 17:23:54ID: 20819904

conf t
int fe4
ip nat outside
exit
int bvi1
ip nat inside
exit

 

by: dimitryPosted on 2008-02-05 at 10:36:18ID: 20825477

It passed but it didn't help. Do I need to save it somehow ?

 

by: naughtonPosted on 2008-02-16 at 18:20:35ID: 20912265

when you ran the wireless configuration - did you set it to bridge or to route?

 

by: dimitryPosted on 2008-02-16 at 21:05:47ID: 20913025

I think I set it to route - at least it was my intention.

 

by: naughtonPosted on 2008-02-17 at 01:25:49ID: 20913462

change it to bridge.

 

by: dimitryPosted on 2008-02-19 at 10:03:42ID: 20930836

Can somebody give me please the whole sequence of configuring what I've asked ?

 

by: naughtonPosted on 2008-04-15 at 00:21:47ID: 21356596

hey dimitry,  did you sort this or do you stillneed assistance?

 

by: dimitryPosted on 2008-04-21 at 07:52:13ID: 21402449

Hi,
No it still doesn't work - I can access AP from WiFi and from LAN, but LAN doesn't see WiFi and WiFi doesn't see the LAN.

 

by: Darr247Posted on 2008-04-21 at 19:22:41ID: 21407760

It looks to me like you've made another vlan that's totally different than vlan1/bvi1, and I don't see where the ethernet ports are set to use any of them.

As much work as you've already put into it, I would still recommend wiping it and starting fresh.
Check out this excel file http://downloads.techrepublic.com.com/download.aspx?docid=243375

It has descriptions of what each command does in the next cell over.
If you enable macros you can put your settings in on the Variables tab, then click Replace and it will copy them all to the appropriate fields. You can then paste them in a few lines at a time...
See the whole tutorial at http://articles.techrepublic.com.com/5100-1035-6102399.html

It demonstrates setting up:
Stateful packet inspection firewall
Two virtual Wireless LANs (max 10)
Two virtual LANs bridged to the two wireless LANs
Both Wireless LANs configured for WPA security
One virtual LAN serving as a guest network with restricted access
DSL PPPoE client
DHCP server
Four-port VLAN-capable switch configured to support 2 separate networks

Ignore the DSL PPPoE section if you don't need that, but I'm pretty sure the rest of it will help... the excel file looks especially handy. Be aware there may be errors in it (that I almost think they put in on purpose to make sure you learn something from the tutorial).
