Setup Linksys Routers

Note that some Linksys routers have a firmware bug preventing any port forwarding at all if their firewall is enabled. If you have a Linksys router and problems with port forwarding, try switching off the Linksys firewall temporarily for testing. If it works without the firewall, you router has this bug. Note that connecting to the Internet without a firewall is a security risk, you might consider using a different router.
