867VAE-w internet troubleshooting

Hi,

I've got the attached config connected via adsl and am able to ping from the router to say google but I'm getting no internet connectivity to an attached computer. I'm not 100% sure what I'm missing.

okies so i removed that line as i'm not using zones but it didn't help. exactly the same results. Updated startup-config attached

Weird it you have all the necessary config but still no good

Last one, on the router itself do the ff.

ping 8.8.8.8
show ip route
show ip route track-table
show track
show ip access-list

logs attached :)

Bro, your internet is down. 

1. Your ping to 8.8.8.8 fails
2. Due to unpingable state, default route is marked down, hence no routing table entry
 

okies i i ditched the whole config and started from scratch and now able to access the net :) My next question is  I'd like to keep the network as DHCP but for certain devices ie. access points, nas's, printer etc, i'd like to be able to allocate them an IP ?

FINALLY haha

Anyway, to do that you can configure IP Reservation
Just do this
 

Oh yeah, make sure the IP is not leased to anyone yet to avoid issues/it not working
 

#conf t
#ip dhcp pool DEVICE1
  #host 192.168.10.101 255.255.255.0      -or use full SM
  #client-name <NAME>                     -OPTIONAL: Add description
  #client-identifier 01hh.hhhh.hhhh.hh  -NOTE: 01 -Define as Ethernet


There, NOTE the client identifier always requires 01 at the beginning 
the hh.hhhh.hhhh.hh is actually your MAC Address so let's say you have a MAC of aa:bb:cc:dd:ee:ff then your Client ID is 01aa.bbcc.ddee.ff


TIP: 01 is always included before the leased IP, you can actually See 01 on all the IP leased out just do #show ip dhcp binding

 

 

Thanks for that! Can i load several devices in each pool or is it 1 pool - 1 device?

The IP reservation does not actually need a pool to be configure, as long as it detects the MAC Address it will allocate that IP to that MAC

YOu must configure one DHCP instance per reserved IP


Dont forget to rate :)

Thanks so much! My config is now up and running :) Thank you so much for your help! I've attached a copy of it. is there a way perhaps html or something that i can easily see what devices are connected instead of having to use CLI?

Hmmm..i dont know, the UI is very limited compared to CLI
Anyway, you can always check it XD

#conf t
#ip http server                           -HTTP
#ip http secure-server               -HTTPS
#ip http authentication local


Then UI: https://<LAN IP>

PS: Use IE, or Mozilla, 
The reason why we enabled HTTP and HTTPS is for testing
Try to go to the UI through HTTPS first, if it does not open try HTTP
 

Thanks a lot too ! (Sorry for my bad english). You help me like leontunnie.

Great, thks

No Problem! :D

Don't forget to rate helpful posts as well ^_^

Wait, reviewing it again I can see that
 

interface Dialer1
 description PrimaryWANDesc_Bigpond_ATM0.1
 ip address negotiated
 ip mtu 1452
 ip nat outside
 ip virtual-reassembly in
 zone-member security WAN
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp mtu adaptive
 ppp authentication chap callin
 ppp chap hostname <username>
 ppp chap password <password>
 ppp ipcp dns request

Are you using zone based firewalling? based on your config you have no zone firewall policies/settings configured

For isolation can you remove that configuration and check again?

 

Don't forget to rate our suggestions so everyone can see 
​additionally, this will mark this section answered/closed :D

Also, why do you have two(2) NAT statements going to one interface the dialer? You only need one. Kindly remove one

If possible, just for isolation, kindly remove the 2nd route (in blue) going to Eth0

ip nat inside source list nat-list interface Dialer1 overload
ip nat inside source route-map nat2backup interface Ethernet0 overload
ip nat inside source route-map nat2primary interface Dialer1 overload
ip route 0.0.0.0 0.0.0.0 Dialer1 track 1
ip route 0.0.0.0 0.0.0.0 Ethernet0 253
