No Route to Internet + NAT traversal

Post by dilshad » Mon May 18, 2015 9:43 am

Hello,

Please your help with my two questions :

1- How can I make the VPN tunnel not to rout to the internet since the purpose of my VPN is only to stay connected with my local network. I did the check box " No adjustment of routing table " in the client side but it seems that I don't have connection when asking for any page " google as an example"


2- When I connect to the server, the message below appears and I couldn't know how to "Disable NAT-T"
in the client side.

---------------------------------Beginning of the message I get---------------------------------------

** Connected with NAT traversal - might be unstable **

This VPN Client is connected to the VPN Server 'ACTED-VPN' by using the NAT Traversal (UDP Hole Punching) technology.

NAT Traversal allows the VPN Server behind the NAT-box to accept VPN connections from VPN Client without any port-forwarding setting on the NAT-box.

However, NAT Traversal-based VPN sessions sometimes become unstable, because NAT Traversal uses UDP-based protocol. For example, the VPN tunnel disconnects every 5 minutes if there is a poor NAT-box between the VPN Server and the VPN Client. Some large-scale NAT gateways in cheap ISPs sometimes cause the same problem on NAT Traversal. This is a problem of routers or ISPs. This is not a problem of SoftEther VPN software.

To solve the unstable tunnel problem, you should connect to the VPN Server's TCP listener port directly, instead of using NAT Traversal. To connect to the VPN Server directly by using TCP, a listener port of the VPN Server must be exposed to the Internet by a port-forward setting on the NAT-box. Ask the administrator of the NAT-box, or refer to the manual of the NAT-box to add a port-forwarding setting on the NAT-box.

If this message still remains despite the VPN Server is exposing a TCP port to the Internet, check the "Disable NAT-T" checkbox on the VPN Client connection setting screen."

--------------------------------------------End of Message--------------------------------------------------------

Thank you all for such amazing project.

About question 1, please increase the metric value to 1000 of the virtual NIC.

About question 2, please add "/tcp" after server host name.
