I'm trying to set up NAT on a windows server 2008 r2 instance inside a VPC on AWS.
I've got two windows boxes, A
and B
A
has two network interfaces, one with an EIP attached and can connect to the internet fine.
B
has its default gateway
set to the private IP of A
s 2nd NIC (configured in RRAS as the private NIC)
All NICs are in a security group with all ports open.
I can RDP on to A
, and from A
to B
, but A
and B
can't ping each other, and B
can't route any traffic through A
.
Tracerts timeout on every hop (they dont even hit B
)
Any idea whats going wrong?
thanks
