IS calling external webservice using different IP


We hava a case when different virtual IP are configured for IS.

Base on some configuration we need to call external webservices by using different outbound IPs.

I am interesting in finding some pratical advice in order to address this requirement.

Thank you

this can only be handled by Mapping IP addresses using NAT, talk with your network team.
Application won’t able to do it.

Of course the network part is already in place, I “only” need a way to use the correct interface for each partner whan calling the webservice.

is there anyway I can specify what interface to use in outbound calls?

thank you
