If you are using static, then you could try your local netmask from 255.255.255.224 (/27) to 255.255.255.0 (/24) or so in such a way that it encompasses both networks. I think this is the simplest to start with. If this has problem, you could always alter the packet using iptables to send it though your second network connection.
