Cisco AussieBB FTTC NBN Config
We had AussieBB install an FTTC service to our premises, it took a little bit of poking to get going, here’s what we found.
Note: we put the NTD into our switch on it’s own vlan (999) so that we could send it elsewhere without having to pull cables out. Another Note: FTTC is shared between up to 4 premises, if you are the only one on the FTTC unit, it might take 5 mins to boot-up - this is because your NTD powers up the FTTC unit (reverse phantom power) and it takes a bit to boot. If it does not come up immediately, don’t panic, make a coffee and come back.
public interface - we had a 100mbit/40mbit service. it comes into the router tagged on vlan 999.
! interface GigabitEthernet0/0.999 description outbound bandwidth 100000 bandwidth receive 40000 encapsulation dot1Q 999 ip address dhcp ip nat outside ip virtual-reassembly in end
if you don’t do that with your switch, your interface would look like this instead.
! interface GigabitEthernet0/0 description outbound bandwidth 100000 bandwidth receive 40000 ip address dhcp ip nat outside ip virtual-reassembly in end
default-route… this is something to note, it comes in via DHCP.. so you need this command
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0.999 dhcp
your lan interface should look like this
interface GigabitEthernet0/1 description LAN ip address 192.168.0.254 255.255.255.0 ip nat inside ip virtual-reassembly in end
and your nat stuff should look like this (replace 0/0.999 with your actual interface)
ip access-list extended nat-fttc permit ip 192.168.0.0 0.0.0.255 any ip nat inside source list nat-fttc interface GigabitEthernet0/0.999 overload
and finally - a port forward for good measure (add as many as you want (111.xxx.yyy.zzz is your PUBLIC IP, this forwards port 443 through to 192.168.0.1 internally)
ip nat inside source static tcp 192.168.0.1 443 111.xxx.yyy.zzz 443 extendable
