Yup. That's how "gate" works.

That indicates you haven't set the LVS up correctly. In a NAT ("masq")
setting, all return traffic from the realservers has to return via the
director so the NAT can be undone.
The easiest way to do this is to set the default gateway on the
realservers to point at the appropriate corresponding interface on the
director.
This is fundamental, and well documented.
