Hi all,

Can you please help me to figure out how to get IP address from ISP fiber modem ?

The modem looks exactly like the one on attached photo.

What i did is i connected 2851 router through GE0/1 interface to GE1 interface on modem.

My router configuration is like this:

Hi

Please make sure that the cable is connected and keep it connected and then reboot your modem.

Regards,

HK

lukaszdobrzanski · ‎12-08-2014

Hi,

The cable is connected however orange light is blinking instead of green.

Reboot of modem did not help.

John Blakley · ‎12-09-2014

This is a shot in the dark, but cable providers usually only assign an IP address to the first mac address that it sees. From there, you have to nat your connections out.

So, for example, if you had a different router on this modem and then disconnected it and connected the Cisco, the provider may still think that the address that it assigned belonged to the old modem. If the interface is coming up on the Cisco router, it's not a crossover cable issue, and it looks like you have the correct config if you don't have to send pppoe information or anything like that. What you could do is to disconnect the router from the modem, or turn everything off, for about 15 minutes. Turn the modem back on and then the Cisco. If that doesn't work, you may have to do some debugs to see what's going on.

HTH,

John

Ok so partially I've got it working, however i'm still not able connect to the internet from my computer.

What i did is sub interface with DHCP assignment and Vlan 10 tagging - my ISP settings.

From this point i can get external IP address.

interface Gig0/1

description WAN

no ip address

duplex auto

speed auto

interface Gig0/1.10

encapsulation dot1Q 10

ip address dhcp

ip nat outside

I think i need assign ip nat inside for my DATA VLAN however its not working. What i did is:

ip access-list standard UFB.NAT.INSIDE

permit any

ip nat inside source list UFB.NAT.INSIDE interface Gi0/0.110 overload

Than on the interface i assigned ip nat inside:

interface GigabitEthernet0/0.110
description Data VLAN
encapsulation dot1Q 110
ip address 10.110.0.1 255.255.255.0

ip nat inside

My switch config is:

Any clues ?

Try changing your NAT acl to -

ip access-list standard UFB.NAT.INSIDE

permit ip 10.110.0.0 255.255.0.0

and retest.

Edit - it may be a typo but you also need to make the following change -

ip nat inside source list UFB.NAT.INSIDE interface Gi0/1.10 overload <--- at the moment you have gi0/0.110 as the interface

Jon

lukaszdobrzanski · ‎12-15-2014

Hi John,

I have tried your suggestion but unfortunately didn't work.

The correct command is:

ip access-list standard UFB.NAT.INSIDE

permit 10.110.0.0 0.0.255.255 (wildcard)

Also i use physical interface Gi0/1 for connection to modem WAN and physical interface Gi0/0 for internal network and is connected to switch. So, ip nat inside has to be assign to Gi0/0.110 - my DATA network.

Please correct me if i am wrong.

Jon Marshall · ‎12-16-2014

Apologies, I forgot the wildcard.

So you need to use the acl with the wildcard.

As for the other part of what I posted. Yes you have applied the correct NAT statements to the correct interfaces so they don't need changing.

It is the actual statement I posted ie. you have referenced the wrong interface.

Please reread and if it's still not clear then let me know.

Jon

lukaszdobrzanski · ‎12-17-2014

Hi John,

Eventually i have started getting something on the router, however i cannot still access internet from my computer or even ping any external IP from the switch.

So my router config now is:

RtrPod1#show running-config

After typing this command i get:

And this one - it only confirms i get external IP on the router:

What is going on ?

Jon Marshall · ‎12-17-2014

Your acl is wrong again.

Can you modify the acl again to use the subnet and wildcard mask.

Jon

lukaszdobrzanski · ‎12-17-2014

I have tried with:

ip access-list standard UFB.NAT.INSIDE
permit 10.110.0.0 0.0.255.255

but still nothing

Jon Marshall · ‎12-17-2014

Sorry to be pedantic but when you tried with that acl had you also updated the NAT statement as I requested ie. where i said you needed to change the interface.

Your current configuration shows that the statement is now correct but i was wondering if when you tried the updated acl you hadn't updated that statement.

Hope you see what i mean.

Can you confirm one way or the other.

Also i assume you are testing from a client in the 10.110.0.x subnet ?

If so how far can you get with the ping ?

Jon

lukaszdobrzanski · ‎12-20-2014

Hi John and Vishal, sorry for late replay as I was away.

So after show ip route and show ip interface brief I get:

RtrPod1#show ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

118.0.0.0/22 is subnetted, 1 subnets

C 118.92.12.0 is directly connected, GigabitEthernet0/1.10

10.0.0.0/24 is subnetted, 3 subnets

C 10.110.0.0 is directly connected, GigabitEthernet0/0.110

C 10.111.0.0 is directly connected, GigabitEthernet0/0.111

C 10.115.0.0 is directly connected, GigabitEthernet0/0.115

S* 0.0.0.0/0 is directly connected, GigabitEthernet0/1.10

BRI0/2/1:2 unassigned YES unset down down

Service-Engine1/0 unassigned YES NVRAM administratively down down

NVI0 10.110.0.1 YES unset up up

Also I can ping from my computer default gateway and external interface with assigned IP by ISP – in this case 118.92.14.89 .

I cannot ping 4.2.2.2 from the router.

Interesting thing is that if I use permit 10.110.0.1 0.0.255.255 than I do not get any output in:

show ip nat translation

However I do get something with ip permit any

Very strange

vishal vyas · ‎12-17-2014

Please try to ping 4.2.2.2 from your pc.

I also noticed that you are not assigning any DNS server under DHCP configuration

Please do these 2 steps and keep us posted

vishal vyas · ‎12-17-2014

When you use /24 mask, you can make changes in 3rd octet not in 2nd octet

Please check your ip scheme.
