Question about forwarding data from Splunk to 3rd party systems

Good day fellow Splunkers,

I have configured to forward data from a Splunk indexer to a 3rd party system (doing index and forward). My questions would be:

1. Upon checking UDP connections shows that Splunk opens at least 20 connections to forward the data. Can this be limit to just 1? (I used port 514)
2. Upon establishing TCP configurations to forward the logs, Splunk opens a lot of connections to the 3rd party system. Can I configure to balance the connections by making 2 ports to be used in forwarding. (1st half would be on port 514 the next half would be on port 515 but the same server IP and same sourcetype - just only 1 sourcetype)

Thanks
