Hi michael_lee,
this is not a Splunk problem, this is based on the so called privileged ports. The TCP/IP port numbers below 1024 are special in that normal users are not allowed to run servers on them. This is a security feature of your OS, in that if you connect to a service on one of these ports you can be fairly sure that you have the real thing, and not a fake which some hacker has put up for you.
If you want to use the port 800 with Splunk inputs, create a new Splunk tcp input on port 1800 and use a iptables rule to route input for port 800 to the Splunk port 1800:
/usr/sbin/iptables -t nat -A PREROUTING -m tcp -p tcp --dport 800 -j REDIRECT --to-ports 1800
Your Sysadmin can do this for you.
Hope this helps ...
cheers, MuS
