Need help about dedicated server UDP encryption

Hi there!

First i hope i post on the right place and there is no topic like this.

Im developping an mmorpg and i would like to use home made UDP proxy to forward user on the right dedicated server depending of the map he is.
I had no problem to make that proxy but i need help for UDP decryption, since it’s seems encrypted.
I tryed to look in project settings if there anywhere i can set the key used for encryption but im not abble to find it and i didnt find good ressource about it so.

Why i need to decrypt UDP packet ?
Well when i call openlevel i would like to pass extra parameters to tell to the proxy where he have to redirect connection for exemple:

openLevel(“127.0.0.1:8888?world=1”)

If anyone can help i’ll really appreciate.

Thanks for reading me and have a nice day!

ps: Im not english native so im really sorry for grammar mistake and anything else, i hope i can be understand.
