How can the server visit internal network?

[Laruto]

I developed ipsec-vpn on my server and connected to it. Then I found that the internal network can visit the server,but the server can't visit the internal network.
How can I do to solve this problem.

Duplicate of hwdsl2/docker-ipsec-vpn-server#141. It is generally difficult for the VPN server to access the subnet behind the VPN client(s) (your use case). On the other hand, it is easier for the VPN client(s) to access the subnet behind the VPN server. See: "Access VPN server's subnet" [1].
