HLDS binds itself to 1 IP and only 1 IP. You can attempt to bind it to 0.0.0.0 and see if it will then accept traffic from both. If it doesn't, you can always try and use iptables to redirect the trafic, I've never done it with IPs before, just ports.

If this doesn't work, then you will need to accept that it is not possible
