The IP-6600 is an industrial rated asynchronous router featuring two serial ports and two ethernet LAN ports. 

Since each ethernet and asynchronous router serial port is independent, the router has many uses in addition to the commonly used dial-in, dial-out and asynchronous LAN connection modes. It is commonly used as an easily configured stand-alone firewall router using NAT, port filtering, and address filtering.  

The two RS232 serial ports operate at asynchronous speeds as low as 300 bps and as high as 230 Kbps.   They may be used to link two separate remote sites with leased or dial connections, one port used for an ISP connection and the second for dial-in, each used for combined dial-in and dial-on-demand dial-out, or other convenient combinations.  

The two ethernet LAN connections (one operating at 10BaseT and the other auto-switching at 10 or 100BaseT) may be configured on different LAN segments for DMZ routing, firewalling and port/address filtering, or used as a DSL or Cable modem adjunct for Network Address Translation (NAT) or PPPoE.    

The IP-6600 works well with DSL, cable or dial modems, leased line modems, CDPD or GSM modems, wireless links, satellite modems, the DCB DA-56 DSU, or even simple line drivers. The IP-6600 is easily configured as a back-up router or fail-over router by adding a second link while configuring interfaces.  

Flexibility is the key.  Routing may be configured between any combination of interfaces with full-featured port or address filtering, port forwarding, and NAT.   The same port may even be configured for dial-out using dial-on-demand while accepting dial-in calls from portable computer users.   It’s easily configured for “stay-online” dial connections.

Firewall Router founctions are easily implemented with the port-filter firewall configuration, port redirect, and NAT router configuration. These make it an ideal small firewall hardware device or NAT router.
Configuration is quick and easy using a web browser.  The router uses three different configurations: a stored configuration, a working (running) configuration, and a pending configuration.  This method allows temporary configuration changes, testing, and remote configuration changes even via a PPP link on the router.  Configurations may be saved on a PC for later use, and the config file is editable on a PC.

On-board tools make network monitoring and troubleshooting convenient. Tools include a packet header sniffer, traceroute, ping, and dial tools (force a dial, force a disconnect). Logging may be configured as standard or with extreme details showing negotiations, modem responses, etc. .

One serial port may be used as a UDP terminal server. This functionality is compatible with DCB's EtherPoll products and is ideal for remote industrial installations.

The APS-01 remote AC power control easily integrates with the IP-6600. Remotely power up, down, and reboot remote equipment using the IP-6600 management web interface by plugging the APS-01 into the second serial port.

The IP-6600 is straight-forward, rugged, easy to configure and maintain.  The IP-6600 has the features you want without  the complexity.

The IP-6600 has been assigned National Stock Number (NSN) 7025-01-555-9076
