TCP or UDP for virus attack!?!?!

[jolo07310]

Recently, we create WLAN, but we dont have any security now.

But, we only allow user to surf web only... We try to deny all virus, worm, dos that attack router using tcp or udp port.

I found a lot of port number at norton website..

Is anyone know the most common tcp or udp port?

Thanks

Hi, don't worry now you will not face these types of issue. As I am personally using it for Sub contracting service. Everthing is working fine. These issues fixed in the recent updates. Just try it now and you will not see such type of issues.
