Easy way, use srcnat/masquerade for connections forwarded to client. It will change source to router’s (VPN server’s) address, so client will be sending responses back to there, instead of using own internet connection. Downside is that client won’t be able to see original source addresses.

Hard(er) way, configure client to route responses back the same way from where requests came. Depends on client’s capabilities, not all are able to do it.
