I just have one router, and my friend (who I think he is the ISP) is giving me Internet. This is the Trace route: 192.168.1.1(my router) 172.30.0.2( my friend pfsense) . .

I just need to know, because it's giving me micro lag in competitive gaming like league of legends, if I disable it, I will lose internet connection, my pre-historic router TL-WR841HP V2 was working...
