Today’s network administrators face the constant challenge of providing users with information-sharing capabilities and Internet access, while maintaining the integrity of their enterprise networks. To meet this challenge, SuperStack® II NETBuilder® SI (secure Internet/Intranet) platforms provide complete protection from outside intrusion with two auto-sensing 10/100 BASE-T ports and an extremely easy-to-use ICSA-certified IP firewall. The routers also future-proof your network, fitting into any WAN environment and providing all the functionality you need for migrating regional and branch offices to Fast Ethernet or new WAN services. They offer industry-leading flexibility as the only remote device with two WAN and two LAN ports, plus a telco connection.  The platforms also provide comprehensive legacy support including DTE/DCE, polled async, BSC, SDLC, and QLLC, so they function effectively in even the most complex IBM networks.

• The industry’s most flexible, easy-to-use ICSA-certified firewall, combined with Network Address Translation (NAT), gives your network ultimate protection from access violations from the Internet

• The SuperStack II platform provides uncompromising, predictable system performance along with SuperStack II Advanced Redundant Power System protection against power failure

• Installation is easy with 3Com’s Boundary Routing® system architecture, which sets the standard for routing simplicity and installation at the remote site

• Based on industry-accepted standards, the platforms communicate and interoperate with virtually any vendor’s products

• The new SuperStack II NETBuilder SI VPN Starter Kit gives you everything you need to begin setting up a cost-saving, Internet-based extranet infrastructure
