tcp - Dynamic DNS port forwarding -

-

i need use computer server isp blocks port 80, 21, 23 etc. can use other ports , dynamic dns service don't want:

i believe need kind of dynamic dns service points router forwards tcp packets address changing ports. know online service that?

many "dynamic dns companies use http redirection send browser port 80 different port. when ask dynamic dns company point domain port other 80, point domain own web-server ip address (in dns), , on web-server (running on port 80) have simple server side script redirects browser web-server on whatever port specified - optionally "cloaked" visitor won't notice." can specify tcp/ip port number web-server in dns? (other standard port 80)

here's reference article redirection script: redirect script.
