cannot connect to computers visible to VPN server

[griznet]

Using amazon EC2.
I can connect to SoftEther VPN server on Amazon EC2 using an elastic IP (54.187.185.154) from a windows pc client at home. But from home (vpn client) I cannot see the internal computers visible to the vpn server (10.0.0.x). I look at the vpn interface on my pc and it is assigned 169.254.193.45). Shouldn't it be in the 10.0.0.0 range?

I have local bridge set to etho which has 10.0.0.0 as the gateway.

You must not use a local bridge on a (v)server.
It's like you plugged your client directly in the networkport in amazons data center. And because your device isn't valid for the switchport, you get no address.
(169.254.x.x is a LinkLocal address)

You have to use SecureNAT or create a bridge with a tap_device and make SNAT with iptables.
Good tutorials are:

And if your EC2-Server running linux, you also can't connect other services on the vpn-server through the vpn (see manual 3.6.11).

Hi Qupfer, Thank you for the quick response. I did as you suggested and it worked.

For reasons that are really beyond discussion, I also put a Windows Softether client in a different Virtual Private Cloud on Amazon ( a Virtual private cloud different from the one the SoftEther Server is on). However, then when I use the same technique to connect to the Softether server, I lose my connection to the the Windows Softether client.

any ideas?

Simple question: Did you use the same username/password for both connections? If yes, this is the poblem. Just create a new user for the second client.

If not, please be more "exactly" ;)
I don't understand, which connection(s) you lost.
If I'm correct, you have three devices?
1: a (linux???) Server hosted in amazons cloud
2: a (windows) Client hosted in amazons cloud
3: a Client at home/work or somewhere else

So, which connection will be lost, and how did you notice that? Specially for the "cloud-client".
I mean for example, if you are using RDP and start the vpn connection, a rdp-disconnection will be normal because new routes are set.

Hi Qupfer,

Once again thanks for your support. I am sorry I was not clear in my earlier email (too early in morning for me. :-))

Anyone, here is the situation, and I have repeated it several times to make sure it was not a quirk.

1. I have a Virtual Private Cloud#1 running Amazon Linux AMI. On it I have the SoftEther Server. It is setup to connect to computers I also have on the VPC#1.

2. From home, I have a Windows 7 box where I loaded the SoftEther Windows Client and can easily connect to the server and see the webpage I was after. I then disconnected this session.

3. Now I create a new Virtual Private Cloud #2 with Amazon EC2. With that I put an instance of Microsoft Windows Server 2012 Base. On that I also load and execute the SoftEther Client. When I go to connect to the SoftEther server in VPC2, it seems to connect (as I can see it from server manager). However, I lose my RDC. No matter what I do, I cannot get the RDC back. I have to stop/reboot the instance to see it again. The connection appears to stay connected to the SoftEther server, but I cannot reach the client machine at all.

On the client I and using the default VPN adapter that it creates. I am also using an elastic IP to connect to both the client and the server.

THANKS IN ADVANCE FOR YOUR HELP!!!!

I figured out that I can connect to device through another computer on amazon's internal network.
