In Solaris, the available range of TCP/IP ports is 0 to 65535. However, there are some restrictions that apply:

Ports in the range 0 to 1023 are reserved for privileged (root) services, such as telnetd, ftpd, and so on.

Ports in the range 1024 to tcp_smallest_anon_port-1 are used for user services such as NFS server daemon, FONT server, and so on.
This leaves the range 32768 to 65535 available for general TCP/IP connections. To limit the range of the port numbers allocated for the general use, the following two ndd(1M) parameters can be used:
tcp_smallest_anon_port:
This determines the smallest TCP port number that may be used for an anonymous connection. Solaris allocates anonymous ports above 32768. The default value is 32768.


tcp_largest_anon_port:
This is the largest TCP port number that may be used for anonymous connections. The default value of this is 65535.
You mention port 80 - are you trying to change where http will be going? If so, you can change to port inside (example Apache) the httpd.conf. If not, give more information on what you are trying to accomplish.
