what tcp port is PXE listening when booting via http

[trzczy]

I changed PXE booting from TFTP to HTTP transfer protocol but I got a TCP port problem.

Webserver i use is the FreeNAS server and it require to enter a desired TCP port number. In the HOWTO i have is nothing about the port number. The howto is for Apache server.

My question is what TCP port number should one enter during PXE webserver configurating when it is required ?
Thanks

The default http port is 80.

You can use an other port if you want. The server port must be used in the bootcommand.
netboot=http://ip:port/path/sysrcd.dat
