Little Help - SynFlood and Udp_flood

[brupj]

I need a little help with firewall and router pfSense.
How to protect and DoS Attack Synflood?

I am getting several attacks on my server.

I use pfsense as fringe firewall and routing.

My server is Steam games … as Counter-Strike, Team Fortress 2, etc. ..

Are you sure its an attack?
You are hosting a gaming server that many players query to get info to their ingame server browser.
You are supposed to get a lot of queries if you host gameservers.

Just a thought.
