Why can't FreeBSD see DNS servers?

Question

Domain Name System

The car with a fryakha sits under NAT. The machine has two setevukh - Realtek and 3Com. On the router, a static IP is attached to 3KOM. When the cable is connected to the tricom, the LAN lights are lit on the router, ifconfig gives the active status to xl0. But pinging, for example, Yandex or 8.8.8.8 does not work - No route to host. SSH also doesn't work. If you connect the second cable to the realtek, the LAN lights are lit on the router, ifconfig gives the active status to rl0 and xl0. Everything responds, everything is as it should be. But here, via SSH, it turns out to connect both via the Realtek dynamic IP and the static Tricom one. It is advisable to use it as a main network with a trick and with such a static IP.
What to do?
Thanks in advance to all who answer!
PS: If it's important, the TrendNet 651BR router (there are no alternative firmware for it, if anything), OS - FreeBSD 10.1, downloaded from the office. site.
PPS: It is fundamental to use one cable, I don’t want to divide it into two of 4 cores - you need the speed of file transfer over the network.

Answer 1

show ifconfig and netstat -rn from a BSD machine.
Yes. and /etc/rc.conf too.
Yes, and more. Two interfaces will not increase the speed of file transfer over the network. More precisely, you can increase it a little, but only if you have many clients downloading these files.
