Easily turn a Ubuntu-based computer into a full linux router, complete with dhcpd, named/bind, iptables firewall, and packet inspection of the network traffic being routed. Deep packet inspection for layer 2 (mac), layer 3 (ipv4, ipv6), layer 4 (icmp, tcp, udp), and layer 7 (application-specific). Summary of network flows and all layers of inspected traffic is stored in a database at 1-second intervals. This database is then mined to drive the Apache/PHP web interface.

Ready to use OpenWRT NAT router appliance for ©VMWare ©ESXi. You only have to uncompress and register it to your ©ESXi server to be able to use it as a fencing device between your LAN network and some NATed network inside your ©ESXi host. It can also be easily configured to serve as a firewall in a dedicated ©ESXi host. You can follow the setup guide at https://33hops.com/vmware-esxi-nat-with-custom-firewall.html The appliance comes in a very small package (less than 5 MB), still it's fully functional, make not mistake. It is configured with 256 MB of RAM in a 50 MB .vmdk disk, which should be more than enough for any small lab, corporate department or (c)VMWare (c)ESXi dedicated server. Just uncompress and register, enjoy.
