hello i would first like to say i a complete networking novice. Aside from few basic things, and my wireless I barely use myself ( aka if my parents internet works and not broken we all don't really care).
Anyways I have and upgraded to d-link dir 655 and ever since my old netgear router used to turn off spi firewall because of a crap ton of problems i had with final fantasy 11 way back in 2004, and bittorrents never worked right even after port foward.
Anyways fast foward to today and I tried to port foward Utorrent, and every time i did the check for ports i always get message that says its blocked.
so i tried to disable SPI and it magically worked.
1) is SPI firewall really necessary ? I am running norton internet security 2012 for firewall and windows firewall so I don't feel like i need any extra protection.
2) will my internet performane slow down or increase for turning this off?
3) from what i read this makes the router not need to port forward? is this true or will I still have to forward ports anyways?
any information is appreciated.
