Just make sure ports 2456, 2457, and 2458 are open for Valheim to run smoothly.
I've hosted a Valheim server and can confirm it uses the default ports 2456, 2457, and 2458. Open those up and you're good to go!
Valheim uses UDP port 2456 by default, but also uses 2457 and 2458 for server communication. Make sure those are open in your firewall!
