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.

so:

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.

Why are you running two software firewalls at once? That can cause conflicts. Only run one software firewall.

At least with DD-WRT, SPI firewall does not block port forwarding. Manually open ports or enable UPnP (less secure) for port forwarding.
