Dual IP servers can only be accessed through one IP, but other IP servers on the same network segment can be accessed.

as shown in the figure:
there are two PC, with IP beginning with 10 (hereinafter referred to as 10PC) and one with IP starting with 192 (hereinafter referred to as 192PC).

there are three servers, all with 10 IP, one of which has 192IP.

the current situation is that
10PC can access three servers through the IP at the beginning of 10 (shown by the green line);
192PC can access the first two servers through the IP at the beginning of 10 (shown by the green line), but cannot access the third server (shown by the red line);
192PC can access the third server through 192IP (shown by the green line).

excuse me:
Why can 192PC access the first two servers through IP at the beginning of 10, but not the third server in the same way?

what should I do if I want to enable 192PC to access the third server through the IP at the beginning of 10?

there are no network topology nodes such as gateways in your diagram, so I can only guess.

I guess it is possible that your gateway did not connect the 10 network segment with the 192 network segment, so the 192 network segment itself cannot access the 10 network segment. When 192pc accesses the 192 servers, they themselves are in the same network segment, so it is normal to be able to access them.
