How to set outgoing IP ?

[sky37042]

Hello,

The server is configured with multiple IP, how to specify an IP as the outgoing IP?

Thanks

I believe you will have several options.

1. Use the IP_HDRINCL socket option and provide your own IP header - using the desired source address
2. Use the SO_BINDTODEVICE socket option and specify the network interface to bind to - you will have to test this
3. Add a static route to the routing table
