Thanks for the response. I have changed the IP scheme of the internal
interface to subnet 255.255.255.0 and the subnet of the external interface
to
255.255.254.0. I have disabled and reconfigured RAS stating the connection
to
use for the internet.

Those are not subnets,...those are Subnet Masks.
Use 255.255.255.0 on *Everything*

The Subnet is identified by the Net-ID in combination with the mask.
Multiple subnets can (and usually do) have the same Mask. Here is an
example of multiple subnets:

Net-ID=192.168.25.0
Mask = 255.255.255.0
Broadcast = 192.168.25.255
Host Range = 192.168.25.1-192.168.25.254

Net-ID=192.168.26.0
Mask = 255.255.255.0
Host Range = 192.168.26.1-192.168.26.254

Net-ID=192.168.27.0
Mask = 255.255.255.0
Host Range = 192.168.27.1-192.168.27.254

Net-ID=192.168.28.0
Mask = 255.255.255.0
Host Range = 192.168.28.1-192.168.28.254

Avoid the heavily *over-used* lower numbers (like 192.168.1.0).

The External side of the RRAS NAT Box will be a Public IP# (not
192.168.*.*).
The RRAS NAT box will *replace* any other "NAT router" that may be there.
The RRAS box *is* your "router".

If you intend to keep an existing NAT Device then there is no real point in
having the Windows RRAS NAT Box in the first place. It is a waist of time
and is over-complicating the network by introducting a Back-to-back DMZ
where there is no point in one being.
