Proxy password or IP whitelist: which access method?
Password authentication and IP whitelisting both control who can use a proxy gateway, but they fit different network environments.
Use passwords for changing source IPs
A laptop or mobile client may connect from many networks. Credentials travel with the client configuration; store them securely and rotate them if exposed.
Use a whitelist for fixed servers
Submit the server’s actual outbound public IPv4 in Access and wait for administrator activation. NAT or a VPN may change the address seen by the gateway. Password-free access works only after the entry is confirmed for the assigned service. Confirm country and session options separately; a source-IP allowlist does not send username parameters.
Limit exposure
Cancel unnecessary pending requests. For an active allowlist entry or exposed credentials, ask support to remove or replace the access and wait for confirmation. A shared office or VPN exit can be used by more people than expected; authorize it only if you control who can connect.
Worked example

Password-free access works only after the entry is confirmed for the assigned service. Confirm country and session options separately; a source-IP allowlist does not send username parameters.
Common questions
Do I need both a password and an allowlist?
Submit the server’s actual outbound public IPv4 in Access and wait for administrator activation. NAT or a VPN may change the address seen by the gateway. Password-free access works only after the entry is confirmed for the assigned service. Confirm country and session options separately; a source-IP allowlist does not send username parameters.
Why does a server fail the allowlist check?
NAT, VPN or a provider gateway may send traffic from a different public IPv4. Test from the server and compare it with the stored entry.
