# The server you are connecting to is using a circuit in order to separate entry IP from exit IP
# The same entry IP allows to connect to multiple exit IPs in the same data center.

# If you want to explicitly select the exit IP corresponding to server US-FL#108 you need to
# append a special suffix to your OpenVPN username.
# Please use "dOadaFR_R45zkxXB0d-6hwp9+b:7" in order to enforce exiting through US-FL#108.

# If you are a paying user you can also enable the ProtonVPN ad blocker (NetShield) or Moderate NAT:
# Use: "dOadaFR_R45zkxXB0d-6hwp9+b:7+f1" to enable anti-malware filtering
# Use: "dOadaFR_R45zkxXB0d-6hwp9+b:7+f2" to additionally enable ad-blocking filtering
# Use: "dOadaFR_R45zkxXB0d-6hwp9+b:7+nr" to enable Moderate NAT
# Note that you can combine the "+nr" suffix with other suffixes.
