Would you please tell me why in the subnet router 1 segment can access 0 upward segment?

My network as shown in figure
Now computer input B IP access to A computer, why? How to let he can't access?
Routing is B tplink wr886n wireless router, opens the wireless capabilities,

CodePudding user response:

IP how to allocate ah, how much is the subnet mask?

CodePudding user response:

Routers B itself has three layers forward capability,
You ping computers in the computer B A, caught look, there is A middle process - gateway router,

CodePudding user response:

Such thing as tp can achieve your result? Seems to be no way! If you want to pursue anything technically that hope you make a point never routers, tp the or for on the Internet,
