openvpn firewall and tap adapter need techie to help me

so i'm used to running openvpn on a ddwrt router, now i'm installing it on my desktop. 

 

all the openvpn docs say i need to completely disable the firewall for the tap adapter, how do i do this with norton? do i need do to this with norton?

 

ok, i'm running openvpn to listen on port 1194 for udp connections, do i need to forward this port in norton and my router or just my router or just norton?
