IPV4 metric settings?

[noisebomb44]

Long version

 

so since i wanted to play warcraft 3 with my friend a few days ago, i looked up a video online to tell me how i can connect to him via hamachi (because battle.net i flooded), it didnt tell me that much, but one guy in the comments told me to change the metric inside the hamachi IPV4 connection to 1. This means that hamachi will be the number 1 priority, and gets to take the shortest route (i think), when i first did it, it worked really well, and i was now able to connect to him, but the next day my internet connection was broken, and as it turned out, it was me setting the metric to 1 that made my internet stop working. when i change it to 1 now, some of my chrome tabs stops getting internet acces.

 

Does anyone know why this is, and how i can fix it?

 

Short version

 

i changed hamachi metric to 1 instead of 9000
my internet didnt work
if i change it to 1 now, some of my chrome tabs will not get internet acces

how will i fix this, but still keep hamachi at 1, and why did it happen?

Open a cmd, run:

route print

And paste it here, although I suspect what is going on

 

When Windows has to send a packet to another computer in the network, if that computer is not in the same LAN, the packet needs to be relayed to a different device (most likely your router). Hamachi creates a tunnel, and although in the end the packets will go to your router, for all intended purposes, for windows you have two different cables connecting to your computer, one coming from your router and one from Hamachi. Changing the Hamachi metric is a bad idea, as it will tell windows to use the Hamachi interface for all the outgoing packets, and as you saw, once you reboot, Hamachi is not even able to connect anymore (as you set him as the default gateway, it tries to establish a tunnel using the tunnel... bad idea

 

Anyway, do not touch the metrics of your computer if you don't know what are you doing. If you use Hamachi only to play with one friend, you could set the metric to 1 to that specific ip (ask your friend for his hamachi IP and run):

route print

(Find the gateway for Hamachi(in the gateway list, the one now marked for 0.0.0.0)

route add <FriendIP> netmask 255.255.255.255 <HAMACHIGateway> metric 5
