I'm setting up a vision system using Ubuntu 16.04 with a number of GIGE vision cameras and two local networks.  I have 6 GIGE ports on my computer to try and sort out and I'm not having much luck.  I'm hoping that this is something fairly obvious that I'm missing.To list them out:enp0s31f6: Connects to the university network using dhcpenp1s0: Connects to local instrument LAN (static IP, 192.168.175.x subnet)enp2s0: Connects to GIGE camera (192.168.0.3)enp3s0: Connects to GIGE camera (192.168.0.4)enp4s0: Connects to GIGE camera (192.168.0.5)enp5s0: Connects to GIGE camera (192.168.0.6)My interfaces file so far is:    # interfaces(5) file used by ifup(8) and ifdown(8)    auto lo    iface lo inet loopback# Primary interfaceauto enp0s31f6iface enp0s31f6 inet dhcp# Secondary interface for vehicle commsauto enp1s0iface enp1s0 inet static    address 192.168.175.13    netmask 255.255.255.0    gateway 192.168.175.1    up route add -net 192.168.175.0 netmask 255.255.255.0 gw 192.168.175.1    up route del default gw 192.168.175.1    post-up route del -net 192.168.175.0 netmask 255.255.255.0 gw 0.0.0.0#GIGE Port 1auto enp2s0iface enp2s0 inet static    address 192.168.0.2    netmask 255.255.255.0    gateway 192.168.0.1    #post-up route del -net 192.168.0.0 netmask 255.255.255.0 gw 0.0.0.0    #up route add -net 192.168.0.0 netmask 255.255.255.0 gw 192.168.0.1    mtu 9000The problem I'm having is that the routes are terribly messed up.  Right now they are:Kernel IP routing tableDestination     Gateway         Genmask         Flags Metric Ref    Use Iface0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 enp2s010.64.226.0     0.0.0.0         255.255.254.0   U     0      0        0 enp0s31f6169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 enp2s0192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 enp2s0192.168.175.0   0.0.0.0         255.255.255.0   U     0      0        0 enp1s0Which isn't super helpful, since it now routes all traffic through enp2s0, which is only connected to a camera.  I'm also not sure how to route only a single IP address through an interface.Thoughts?
