UDP remote ports

[Steve92]

Hello,

According to the doc, by default, for UDP, range of remote ports 4011-4999 must be opened on client side.

Is there an impact on performances if we reduce this range to only one port, for example if the client uses many screens ?

What is the best practice ?

Thanks,

Regards,

Steve.

There is no impact on performance and only only one port is used at a time. Reducing the range too much only increases the chance that all the ports in the range are busy, and in that case udp wouldn’t be used.

Hello,

If multiple screens are used, only one UDP port is used ?

how can it happen ?

In our case, only one remote UDP port would be open instead of a range !

In what case can it bring problems ? Give examples please.

Thanks !

Regards,

Steve.

Why does multiple screens affect the number of ports? Do you mean connections/multiple players?

Obviously having a single port in the range would affect the case you run multiple connections from the same client, as only one of them would be able to use UDP. There is also a (small) risk that an external app keeps that port busy.
