Problem:  Network station can't be reached by HUB or any machine if both NICs are on the same network/VLAN

Possible Resolution:

1. Disconnect NIC2 so that you can SSH to the station appliance as friend/sspassword, then su -  (same sspassword when prompted)

2. Paste in and execute the following 4 commands:
echo -e "net.ipv4.conf.eth0.arp_filter=1\nnet.ipv4.conf.eth1.arp_filter=1\nnet.ipv4.conf.br0.arp_filter=1" >> /etc/sysctl.conf

sysctl net.ipv4.conf.eth0.arp_filter=1

sysctl net.ipv4.conf.eth1.arp_filter=1

sysctl net.ipv4.conf.br0.arp_filter=1

3. Reconnect NIC2 and you should now be able to capture traffic and NOT lose network access to the station from your machine or the HUB.
