can't ping ms

[tempest]

make sure it doesn't change - get static ip?
and I went on the screen thing for my router (by entering my ip) but I can't see port forward settings listed

It might be called differently. E.g. for my router, it's "Game & Application Sharing".

Also, many routers let you change settings for devices in the network. If you have an option like "Always use the same address", enable it.
