performance about use Linux as a router

[Tharindu Rukshan Bamunuarachchi]

in this case you are creating STP loop and enable of STP will disable either
eth1 or eth0.

what are you trying achieve ? Is it just sending packets over both ethernet
interfaces ?

you better bond those two ethernet interfaces. you need switch configuration
for proper incoming traffic flow.
