On the server, I installed the VPN using the "setup-ipsec-vpn" script of the hwdsl2 user. I found him here.
As a result of its actions, the script provided me with: User name, password and IPsec PSK code.
However, on the router, I have to put information about Tunnel password, handshake interval and Authentication. You can see the tab with the router configuration here. Unfortunately, I could not find such information (neither at Github nor on the server).
The router is a Huawei B525.
What can I do in this case? Do not complete these fields? Change some configuration in some way?
LNS address: IP (name) of the server
Host Name: Whatever
Tunnel password: IPsec PSK code
Handshake interval: 30s (dpddelay in vpnsetup.sh)
Authentication: Can be "Auto"
