[ts-7000] network problem ts-7800

["sefacanacar" <>]

i trying to connect internet with ts-7800. i made the configuration from /etc/network/interfaces 

auto lo
iface lo inet loopback

auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
        address 192.168.1.50
        #network 192.168.1.0
        netmask 255.255.255.0
        #broadcast 192.168.1.255
        gateway 192.168.1.1
iface eth1 inet static
        address 192.168.1.50
        network 192.168.1.0
        netmask 255.255.255.0
        broadcast 192.168.1.255

but still can not connect to internet. i red in some sites that i must change some parameters in /etc/hostname ,  /etc/hosts files but not written clearly. so how can i connect the ts-7800 to internet?
thanks
