help connecting to my tcp server via public ip

[lIlIIlIllIIIIlI]

hello

using the udf examples, i built out a client/server to understand tcp and how to send and receive stuff. it works on the local network fine. to get it working with my public up, this will just require port forwarding and then reserving my ip since it has dhcp? anything else?

i can never remember my router login so i'm just wanting to learn all the requirements first before i reset it so i can login and change things.

thanks

Correct (and this is based on the limited info given!  )

DDNS, Port Forwarding, and hope you don't get hacked!

A better alternative might be a VPN

is there a risk in using my server using the port provided in the udf, for just sending strings and such? i thought the dangers come from the programs listening to the ports having a vulnerability. i really dont know much about the internet

 

thanks @Jos

There is no risk other than the risk you create. If you only open your PC's IP ( let's call it 192.168.9.123 ) to port 2088. Anything from the internet is going to be directed to 192.168.9.123:2088 and that's not a vulnerability, just a redirection so don't be freaked out.
Anything you send/receive can and will be used against you in a court of law the internet, so don't send clear text.

And that's that. So have fun and learn some new ...  stuff

You asking this question is the biggest risk as you clearly don't yet know what you are getting into!
