Android T650P PED Connection and Firewall Requirements
Problem
Verifone T650P payment terminals require specific network and firewall configurations to successfully connect to Verifone’s POS Cloud payment platform. Users need to ensure that all required connections are enabled for payment processing, device management, and essential background functions. Without these connections, payment processing and other terminal features may not function correctly.
Resolution
DNS Resolution
- Allow outbound traffic on TCP port 53 and TCP port 853.
- Configure access to Google DNS servers:
8.8.4.4and8.8.8.8.
Payment Processing
- Permit HTTPS traffic to:
https://gsc.verifone.cloud/api/v1
- Ensure that both of the following IP addresses are whitelisted:
178.21.210.130178.21.211.130
- DNS queries to
gsc.verifone.cloudmay resolve to either IP address; static whitelisting for both is strongly advised.
- Permit HTTPS traffic to:
POSCloud WebSocket Connectivity
- Allow WebSocket connections to:
wss://emea-pos.gsc.verifone.cloud/poscloud
- Allow WebSocket connections to:
Time Synchronisation
- Permit HTTP access to:
http://time.verifone.cloud/v1/time

- Permit HTTP access to:
Logging Services
- Allow HTTPS traffic to:
https://cgateway-core.verifone.com:443/latest/logs

Notes
- Unlike previous integrations, Verifone T650P devices do not require a direct connection to Gladstone360 POS Hardware Service on local PCs. They only need connectivity to Verifone POS Cloud services.
- Background functions enabled via these connections include payment processing, time synchronisation, log uploads, external connectivity checks, and device management.
- Network/firewall administrators should review this list to ensure all routes are open to avoid connection and processing issues with the devices.
