Firewall rules |
Version V1.62 |
Cynap Pure has firewall rules that must be adhered to in order to allow successful network communications and the corresponding services to be used.
Acknowledgements ("ACKs") of TCP packets are not considered in the following table in order to be able to illustrate the direction of the data packets. Since acknowledgements are usually sent back via the same TCP port, the other direction shall not be blocked to ensure smooth functioning.
To use services with user defined addresses and ports, be sure these are not blocked by your firewall (external and personal).
