Dynamic DNS on non-port 80

[ModusPwnd]

Hello,

I am attempting to use DynDNS so that I dont have to remember IP address. I currently access my home network using IP address with the port after it, ex. xx.xxx.xxx.xxx:53908. I access remote desktops and ftp, each with a different port for different computers. It seems that with DynDNS service I still have to enter in the port after the address? ex. dnsaddress.homeftp.com:53908 This is no good! It does work without the port, as long as I use port 80. But I need many ports available, and I cannot forward 80 to every computer. Maybe that is confusing...

Here is what I would like:
dnsaddress1.com -> xx.xxx.xxx.xxx:53908
dnsaddress2.com -> xx.xxx.xxx.xxx:53909
dnsaddress3.com -> xx.xxx.xxx.xxx:80

But this is what it makes me do:
dnsaddress1.com:53908 -> xx.xxx.xxx.xxx:53908
dnsaddress2.com:53909 -> xx.xxx.xxx.xxx:53909
dnsaddress3.com -> xx.xxx.xxx.xxx:80


I hope my quesiton makes sense. Any ideas or tips you have would be appreciated! Thanks!

I don't really think there is a good practical way to do it, no. You could do it for one port, and have port 80 forward to an inside port of like... 3306 or whatever service you use, but thats it.
