I've just switched to an ISP that requires me to use a router, which is ofcourse a good thing. However, i have no experience with routers but managed to set up a static IP and do some port forwarding for some internet games and applications. But - correct me if i'm wrong - when i forward these ports they they will be open whenever i'm on the internet(?). Does that mean that f.e a hacker can exploit these ports with ease or are they still protected by the router (and NAT)? Secondly, i've read that UPnP is a security hole. Is there any truth in this? I mean, if it's secure enough UPnP would make all this port forwarding alot easier. Last, i'm using Look'n'Stop for app control, is this and the router enough protection (antispy/malware and AV programs excluded)?
