Hi All. I was wondering if someone could assist me with the following.
I have a cisco 867 which I configured to work with ADSL and have had running for the last 12 months. On Tuesday I am getting my NCD for my new FIbre to the Curb FTTC connection and I have tried to modified the configuration to the use of the gigabit WAN port interface GigabitEthernet 2. Now I began and used CCP to do this (and then over the console cable just for testing different running setting) shutting down the dialer and ATMO connection which then brought up the wan (it is set to get an IP via DHCP). I then gave this a nat outside which the dialer interface previously had and then modified the rooting so that all traffic was natted through the new interface.
I have been tenting the config as follows. I have another modem connected to my current ADSL connection and I am then plugging that into the wan on the cisco. The adsl moden has full internet access and if plugged directly into a laptop works fine. When I plug in the Cisco the Cisco pickups an IP on the wan interface gigabitinterface2 (I have set the adsl modem to give out ip’s in the 10.10.10. 2 up to 10.10.10.50 range) but no traffic to outside is being routed to it.
I want to keep the config as it has other static routes etc in it. I can see what’s wrong with it. I have been working on it late in the evening after work so tiredness has probably been my enemy.
If someone could have a look and maybe help I would be grateful. Maybe I need to set the GE2 interface to no ip or maybe ip negotiated as well for FTTC.
Below is the config
Thanks

Hi,
DO you have two vlan's on your LAN meaning is the LAN subnet (192.168.1.0/24) configured on the other working router same as the new router? If so this might be the issue.
Can you post the config of the other working router?
Can you share a brief diagram of your topology?
Regards,
Terence

Hello,
so the modem dishes out 10.10.10.1 or 10.10.10.2. Is this range being NATted on your ADSL modem (which type/brand modem is that ?
You might want to change your NAT configuration on the Cisco as below:
ip nat inside source list 1 interface GigabitEthernet2 overload
--> no ip nat inside source static tcp 192.168.1.230 80 203.219.245.98 80 extendable
--> no ip nat inside source static tcp 192.168.1.205 81 203.219.245.98 81 extendable
--> no ip nat inside source static tcp 192.168.1.230 8000 203.219.245.98 8000 extendable
--> no ip nat inside source static tcp 192.168.1.230 10554 203.219.245.98 10554 extendable
ip route 0.0.0.0 0.0.0.0 GigabitEthernet2 dhcp

Hello,
Thank you all for the reply's.Not to worry. I have it all working. I deleted the settings on the GE2 WAN interface and re did them and the NATS and all good now. I am only using a standard billion adsl modem. I was just using it to emulate the new connection device/modem
I assuming with this config on the wan
interface GigabitEthernet2 description $ETH-WAN$ ip address dhcp client-id GigabitEthernet2 ip nat outside ip virtual-reassembly in duplex auto speed auto
that it should pick up a 1:1 nat from the new FTTC modem
many thanks
