How to make an outgtoing TCP connection through specified netwrok interface?












0















Is there a way to implement in C program a next feature: it's need to making outgoing TCP connections through specified network interface? as example:



eth0 - 172.16.0.1
eth1 - 192.168.1.1



In some case I'm need to make outgoing connections from source address 172.16.0.1, and under some other circumstances from 192.168.1.1.



Is this possible ?
Is this can be achieved with bind() routine?



TIA.

  • Thanks, useful topic. But I'm don't need to bind a listening socket but socket for outgoing connection.

  • Doesn't make a difference. See stackoverflow.com/q/335607/5830574 They also suggest setsockopt().

  • Ok. Thanks again. I just will check it with test code ...

  • setsockopt(#3, SO_BINDTODEVICE, enp0s3:1)->19 - it;s looks like that BINDTODEV is no works for the pseudo-interfaces.
