Hello,

1. Is it possible in some way to remove the routes to the subnet in
which the network adapter resides?
2. Is it possible to somehow forward traffic to a subnet trough a VPN
connection?

I am struggling with the problem of setting up a working VPN in an
environment where the local subnet is the same as the destination one.
I have googled up some solutions but cannot give them a try due to
problems in the above answers.

Any amount of manual work before / after enstabilishing a connection
will do fine, since I can script it anyway.

If VPN will do no good in such a situation, what other technologies
can I use to fix the problem if changing the subnet is not an option.

Thanks for any help in advance!

The only solution is create a peer to peer routing. This search result may
help.
Solution for peer to peer VPN using the same IP
Setup IPSec VPN - VPN using same ip in the different subnet. 3. You
may setup a different IP range or subnet for peer to peer VPN. For example,
in your case ...

Hi,

I will try that.

My second questions is: What about connections that go the other way?

If A is using vpn to connect to network B, how does a computer from
network B connect to a service running on A? I have remote desktop in
mind.

Thanks for any help.
