Hi Everyone,
Thank you for your help so far. Just to let you all know where I am up to, here is an update.
After a hectic week when I was unable to take the link off line, I grabbed an old CISCO 2600 router and threw a base config on it to test. With this config, I was able to achieve a ping on the second IP address.
[CISCO Config]
interface FastEthernet0/0
ip address dhcp
duplex auto
speed auto
!
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 180.150.96.103 255.255.254.0
no snmp trap link-status
Looking at the CISCO config, it is using a default VLAN to achieve the link using the "Framed Route". So I have added a VLAN on my WAN interface on the RB2011 with the VLAN set to 1. I can now ping that address from the internet.
RB2011 Interfaces
0 R ;;; WAN-NBN
ether1-AussieBB-WAN ether 1500 1598 4074
[Cut out irrelevant interfaces]
16 R ;;; DMZ
bridge-DMZ-SW2 bridge 1500 1598
17 R ;;; INT
bridge-INT-SW1 bridge 1500 1598
18 R vlan1 vlan 1500 1594
ip address p
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK INTERFACE

From the internet site

I will now work on the outbound routing from the VLAN interface.
