[SOLVED] Connect to a remote computer that's using a "VPN"

JamesGT · 10-25-2018, 02:08 PM

I have a computer that is running Slackware64 14.2. I want to use sshuttle to connect it to another computer to tunnel it's data through another machine. I can do that successfully. When I do, I lose my connection to it from my own local machine because all data is now routed through another machine because of sshuttle.

How can I connected to a box that has all it's data tunneling to another machine?

Let me see if I understand this. You are connecting from Computer A to Computer B. Once you are inside Computer B, you are tunneling data Computer C to Computer B, but your connection from Computer A to Computer B is dropping.

Is that correct? If not, please straighten me out.

I am sitting at Computer A. I use SSH and VNC to get to Computer B. Computer B is using a VPN (sshuttle) to get to Computer C. When Computer B connects to Computer C through the VPN(sshutte), Computer A loses SSH and VNC connection to to Computer B, but I still want A connected to B.

This may or may not apply, but some VPN software prevents "split tunneling", which is essentially connections outside of the VPN. Not sure if this is the case, I have no familiarity with your VPN software.

I am using "sshuttle". It's kind of a "poor mans" VPN basically using SSH.

I am reading as much as I can about it to see if I can make exceptions for specific IPs to connect outside of the VPN/tunnel.

Posting your configuration files might help. Just sayin.

From the documentation

Code:

-x, --exclude=subnet

    Explicitly exclude this subnet from forwarding. The format of this option is the same as the <subnets> option. To exclude more than one subnet, specify the -x option more than once. You can say something like 0/0 -x 1.2.3.0/24 to forward everything except the local subnet over the VPN, for example.

-X, --exclude-from=file

    Exclude the subnets specified in a file, one subnet per line. Useful when you have lots of subnets to exclude.
