Traffic from OpenVZ host to container gets redirected to gateway

An OpenVZ host (RHEL 6) is running Debian-based containers. The problem is that network traffic, instead of being routed to a relevant container (10.10.104.1) via venet0 interface, gets routed to the host network's default gateway (143.215.76.129). At the same time, traffic to the 192.168.x.x network does not get redirected to the gateway. Relevant output below.
