I bought this router from a friend,
I got the Cisco Configuration Assistant and the Cisco Network Assistant along with the internal java based control application for it. I managed to set up everything I think properly. The Vlan has DHCP set up and it is giving out IP's The Outside WAN interface (Fastethernet4) is set to DHCP and is pulling an IP from my ISP (Cox).
The issue I am having is even though my PC is getting an IP I have no internet access. I made sure NAT was set up to forward unknows to the Fastethernet4 interface. I even turned off the Firewall to ensure it was not blocking me..
Can anyone tell me what I may be missing?
Thanks in advance!

So I pulled my line to test and it came up for like 5 seconds, then went away.. again

Hi Ark,
Do you get an IPaddress from four ISP?
I think you can check with "show ip interface brief" command and see if there is any IP behind fa4.
If you got an IP, you can try pinging an outside IP address from your PC's DOS command window.

Ok so I got it working, i dont know how, but I do know there is 1 more issue with it...
My Download is limited to about T1 speeds, yet my upload is maxing out at 6 megs (As it should)

Anyway I'm happy to hear that your browsing is working .
For the upload/download speed issue I think you have to contact your service provider .It has nothing to do with configuration . Please make sure about your interface speed and duplex .Also please rate the useful comments

Actually, My laptop is on the cisco, when I connect it to the netgear router like my big computer I get 50 megs down, when it is on the cisco 851 its only at 1.5 megs, so I think it has something to do with the cisco 851.
03-16-2011 08:44 AM
Dear ,
Try to check the interface speed on both netgear and
Cisco .It should be 100/Full on both side . If your
netgear is having gig interface ,try to change the
speed to 100/Full manually on both side and please
check the result
Regards
03-16-2011 11:46 AM
The laptop ethernet card is 100/full but I do not know how to change that on the cisco...

I would add this to your config, I may have overlooked it but I did not see a gateway of last-resort.
ip route 0.0.0.0 0.0.0.0 dhcp
Also, on your original reply you mentioned that you were not getting an IP address. I seen that you were blocking 10.10.10.0, when you removed the ACL it worked.
"access-list 101 remark auto generated by SDM firewall configuration##NO_ACES_11##
access-list 101 remark SDM_ACL Category=1

Dependent on Cox network their DHCP/BOOTP servers may be on a 10.x.x.x network. Possibly the 10.10.10.x network you were blocking by your first ACL statement. I know TW I receive my IP via a 10.x address. Look below for reference.
Router871w#sh dhcp lease
Temp IP addr: 24.94.x.x for peer on Interface: FastEthernet4
Temp sub net mask: 255.255.252.0

DHCP transaction id: C3C
Lease: 43200 secs, Renewal: 21600 secs, Rebind: 37800 secs
Temp default-gateway addr: 24.94.x.x
Next timer fires after: 05:29:54
Retry count: 0 Client-ID: cisco-001b.8fxx.a2xx-Fxx
Client-ID hex dump: 636973636F2D303031622E386664332E
Verify for yourself with a "sh dhcp lease"
You may want to place this first on any inbound ACL:
permit udp any eq bootps any eq bootpc
Also, when you do a deny ip any any, you need to configure the firewall feature in the IOS to allow connections that originate inside out.
Example:
ip inspect name FIREWALL tcp
ip inspect name FIREWALL udp
interface FastEthernet4
ip inspect FIREWALL out
Hope this helps and improves your speed.

permit udp any eq bootps any eq bootpc ---- It gave me an error when I put this into the config
You may want to place this first on any inbound ACL:
ip inspect name FIREWALL tcp -- worked
Also, when you do a deny ip any any, you need to configure the firewall feature in the IOS to allow connections that originate inside out.
Example:
ip inspect name FIREWALL udp -- wprked
interface FastEthernet4
ip inspect FIREWALL out -- worked
I did a wr after and rebooted

When you are doing a download, try to download from a server that will max your pipe, as you are downloading issue this command into the router:
sh proc cpu hist
You will get something like this:
Router871w#sh proc cpu hist

If its maxed as you are downloading, you may have reached the limitations of that 851. I'm just curious if you are maxing out your processor on the router.
