you share error log’s screenshot in this post?
you input correct IP address for VPN Gateway?
> VPN > IPSec VPN > VPN Gateway)
you provide remote admin access for both site of IPSec B by private message?
Also the tunnel connection can only be established with the zywall ipsec client tool, and not with the native ipsec client provided by windows or ubnutu, do you think it's a NAT problem ? knowing that my usg is directly connected to internet.Thank you
