DDOS on legitimate port?

[cyberwolfie]

Hi Everyone,

I am new to Pf Sense, but have been experimenting with it.

Can PfSense block udp ddos on a game servers port?
We have a problem where people are attacking port 27015 (Counter Strike Source) port.

I have setup our pfsense box to be transparent and its working in so much as I can add a rule and it lets traffic in, disable the rule andit stops it, so pfsense is working fine.

I am just not sure what the next step is, I would be very grateful if someone can give me some pointers as this is ruining everyones fun playing games :(

Thanks
Andy

When you click the advanced button on the firewall-rule-editing page you can set maximum connections per second / states per client.

maybe you could play around with that.
