Two computers
A 192.168.1.120
B 10.14.234.110

A can ping B, using VB winsock unable to connect, excuse me how to use VB winsock connection to communicate?

Successful scores can add

Can look through this book, this example is more, to test the network (LAN), to test the network (his first need to be able to access the Internet)

CodePudding user response:

Open firewall corresponding port,

Including Windows firewall and other security software installed on the computer network, and between the two connected to the computer through the corresponding port all hardware firewall,

CodePudding user response:

Can even can ping,

But should pay attention to: (1) A can ping B, is not equal to can, in turn, B can ping, typically, A network, B in the Intranet (relative to NAT), so can't take the initiative to connect B,
(2) the firewall Settings, port is being used,

Are both within the segments, the original poster is to realize the network connection (different network segment)

Two computers can ping,

I use 10.14.235.53 can communicate with 10.14.234.110 using winsock, but 196.168.1.120 anyway is not connected to the 10.14.234.110

This ask network management, he give you opened a permission can communication, can't banned,
What customs procedures!

CodePudding user response:

These are two different network, also don't know how to connect between the two net is, if there is a direct physical connection, you can through the router to set the two network routing forwarding.

If the middle also through the Internet... That either side open VPN, and the other a VPN access.

CodePudding user response:

That's no concern of programming language, is the thing of networking,

CodePudding user response:

A computer network card, in a different segment, how realize vb communication at the same time, is a1 communication b, c, a2 communication two segment

Use the WinGate port mapping software,
