I believe that you need to set up DMZ. Follow this guide (https://dreamcastlive.net/connection-guide/) and scroll down to the DMZ section.

You need to port forward some games, or set your DC up in DMZ mode.

Some games may require port forwarding or DMZ in order to play a game once connected. To set up DMZ on your router, go to your router’s configuration page, find the DMZ setting, and input the IP address of your Dreamcast. The IP address of your Dreamcast will be the same as the IP of your router except for the digits after the last period which will normally be 98 (e.g. If your router’s IP address is 192.168.1.1 then the Dreamcast would be 192.168.1.98).

NOTE: Although this is rarely the case, there’s a possibility that another device on your network is already using .98. In this case, the IP will be something else (sometimes .97 or .99). You can double-check the IP address of your Dreamcast with an NTSC-U copy of Quake III Arena. The IP address will be shown after a successful connection.

If you need to use port forwarding instead, here are the ports that you need to forward:

Alien Front Online: UDP 7980
ChuChu Rocket!: UDP 9789
Internet Game Pack: UDP 5656 | TCP 5011 | TCP 10500 | TCP 10501-10503
NBA/NFL/NCAA 2K Series: UDP 5502 | UDP 5503 | UDP 5656 | TCP 5011 | TCP 6666
The Next Tetris: Online Edition: TCP/UDP 3512
Ooga Booga: UDP 6001
PBA Tour Bowling 2001: TCP/UDP 2300-2400 | UDP 6500 | TCP/UDP 47624 | UDP 13139
Planet Ring: UDP 7648 | UDP 1285 | UDP 1028
Starlancer: TCP/UPD 2300-2400 | UDP 6500 | TCP/UDP 47624
World Series Baseball 2K2: UDP 37171 | UDP 13713
Worms World Party: TCP 17219

Want to make sure you set everything up correctly? Below are some issues you may see if your DMZ / port forwarding is not working.

2K Sports Games – You can send game invites but you can’t receive them.
Alien Front Online – You get an error immediately after joining or creating a game and are kicked out.
Planet Ring – Your character’s outfit doesn’t change and the tables are always full.
Worms World Party – You can host games but can’t join them (the game won’t start).
