Hello,
How does one go about handling an overlapping IP?
I understand this question is broader than LibreSwan, but perhaps there is a
solution particular to LibreSwan or ipsec. My own research has left me more
confused than enlighten. I am very new to networking and a slow learner.
The situation is:
Left side is on network 10.0.0.0/16 hosted on AWS
Right side is 10.0.0.0/8 hosted by a third party
Both sides are run by different organizations and are not able to change their
internal networks.
The configuration is
leftid=hidden # conf for AWS
left=10.0.127.5 # Elastic IP
leftsubnet=10.0.128.0/24
right=hidden
rightsubnet=10.0.0.4/32
What perhaps makes this a simpler problem, is the connection is essentially
client based: the left will be connecting to the right, but the right has no
access to the left. And perhaps even simpler only a single IP on the right is
required.
Any advice, or pointers to documentation will be very much appreciated.
Thank you very much - John
