I am using TEQL on two computers, each with two network interfaces. The two eth0 are connected directly, and the two eth1 are connected via a gateway (a linux machine). The problem is that when I send packets through teql0 to the other machine (ping -I teql0), the packets can't go through eth1 and all packets go via eth0. But I can send packets via
eth1 directly (ping -I eth1). What's wrong? Is it because of the routing tables?

I put eth1 and teql0 on one computer, and the gateway interface on the same side into one subnet. I only found TEQL configuration for two direct links. My routing tables are attached below.

I have tried TEQL on two direct connections (without gateway), and it works fine.

Thanks a lot!
