Yes, ports for players are configurable, however the LoginServer port 2106 can not be changed without client modding which is not allowed here(the port is hardcoded in the client, means it is not configurable on the client side). The GameServer port can be any you like, because when the LoginServer sends the GameServer list to the client, it also includes the ip and port in that list.

There are some services out there which are suposed to protect you from DDoS, you can't get a homebrew solution for a DDoS protection. I don't know how thoose services work but a guess is that they act like a proxy between your server and incomming traffic. They could detect DDoS traffic and only send the legit traffic to your server. The more bandwith available, the better the protection against bigger attacks.
Traffic could be balanced over multiple servers. Then you would need multiple servers on their own internet connection which redirect the legit traffic, and in case of the L2 client you would have to rely on DNS round-robin(DNS server has multiple IP addresses for your domain and responds with the list of IP addresses in different sort order each time it is requested). The servers ip address on which the login and gameserver runs is not in the DNS entry and only internally used to forward the traffic from the public available servers to the servers which actually run the game and login server.
However what i wrote above is only theoretical hypthesis without deep logic about that topic.
