# egress_pool The name of the egress pool which should be used as the source of this traffic. If you do not specify an egress pool, a default pool named `unspecified` will be used. That pool contains a single source named `unspecified` that has no specific source settings: it will just make a connection using whichever IP the kernel chooses. See [kumo.make_egress_pool()](../make_egress_pool/index.md).
