i have tried to setup a port forward (eg open a port so i can access an outside computer network which is not always on the same ip)
--> My interpretation. You have a LAN Client on your network behind WinGate and it is trying to connect to a server on the internet.
i keep getting authentication fail on guest from ip: on the port i opened when trying to access the remote pc

1. If you want to use the Guest account for this connection then confirm it is enabled in WinGate.
2. If you are using the NAT connection method, then remember that it has no generic way to pass on a user name and password. So if this server you are trying to connect to is always on a certain port, e.g. 5900, then you *may want to create a policy allowing unauthenticated access.
e.g. Extended Networking Service --> Policies.
Default Rights, May be used instead (or your decision)
Add --> Guest, User may be unknown.
Advanced tab:
Filter 1
This criterion is met if Server Port equals 5900
3. Review the way your LAN Clients authenticate, there are a few ways to do it:
WinGate User Database.
WWW Proxy Java Authentication - Secure method.
WGIC Authentication - Secure method - Client install.
Qbik Authentication - Secure method - Client install.
GateKeeper Authentication - Secure method - Client install.
Basic Authentication - Insecure method.
Assumed by IP Address - Insecure method.
Assumed by Computer name - Insecure method and WinGate must be DHCP Server.
Unauthenticated Access - Can be set for different connection methods or ports.
Local Windows User Database
WWW Proxy NTLM Authentication - Secure method - Applications needs to be NTLM Compatible
WGIC NTLM Authentication - Secure method - Client install.
Qbik NTLM Authentication - Secure method - Client install.
GateKeeper NTLM Authentication - Secure method - Client install.
Basic Authentication - Insecure method.
Assumed by IP Address - Insecure method.
Assumed by Computer name - Insecure method and WinGate must be DHCP Server.
Unauthenticated Access - Can be set for different connection methods or ports.
Domain User Database.
WWW Proxy NTLM Authentication - Secure method - Applications needs to be NTLM Compatible
WGIC NTLM Authentication - Secure method - Client install.
Qbik NTLM Authentication - Secure method - Client install.
GateKeeper NTLM Authentication - Secure method - Client install.
Basic Authentication - Insecure method.
Assumed by IP Address - Insecure method.
Assumed by Computer name - Insecure method and WinGate must be DHCP Server.
Unauthenticated Access - Can be set for different connection methods or ports.
Secure methods need a policy authentication level of "User must be authenticated".
Insecure methods need a policy authentication level of "User may be assumed".
Unauthenticated access needs a policy authentication level of "User may be unknown".
