Connect CentOs To Zyxel USG 100 via VPN IPSEC

simsar78

Hello I have Zyxel USG 100 and I need to connect my ContOS.
I have a many windows 10 connected to Zyxel with this software: "ZyWALL IPSec VPN Client" and it's works.
How I can connect my centOS ?
I no have GUI on CentOS. Only CLI.

I connect windows client with IPSEC IKEv1 whit password.

thanks

Good luck.

I thought you should use L2TP instead of IPSec Client on CentOS.
It seem they will work with xl2tp,ppp package. And you don't need GUI as well.

Thanks you very much.

Can i implement this guide on my CentOS without username e password for VPN ?

I have only PSK and server IP

WJS

In line 56, you might declare PSK for varaibles "VPN_IPSEC_PSK" first,  I'll try that as well .
