When a DNS request is received from a locally attached workstation, the OfficeConnect Remote 812 will search the local static table to find an entry. If one is not found, the request will be forwarded to a Remote DNS Server. The DNS Server is selected by comparing the domain name within the Request. If the Request was for www.MyCorp.com/events/local the domain MyCorp.com would match given our configuration and the request would be forwarded to the DNS Server at 192.168.1.253. If a request was for www.3com.com, a match would not be found in the Remote server table and therefore the request would be forwarded to the default Remote DNS Server. In this case, the Remote DNS Server is dynamically learned when the connection to the remote site “Internet” is first established.
After a workstation is rebooted and is configured automatically by the OfficeConnect Remote 812’s DHCP Server, the 812’s
LAN IPX Network The local IPX Network is defined with a Network Number of 10 and an identifying Configuration name of “ipx”. Routes and Services will be dynamically learned using RIP and SAP
once the Remote Site to MyCorp is established. The following commands are executed:
add ipx network ipx address 10 frame ethernet_ii enable yes
set ipx net ipx rip both sap both
Bridge Configuration A Bridge network is configured for the LAN. With our example, IP and IPX are routed over the Corporate Remote Site and all other protocols (e.g. AppleTalk) will be bridged. The Bridge network is added with the following commands:
disable bridge spanning_tree
add bridge network bridge
Remote Site: Internet In our example, we have two defined Remote Sites. In this section, the Remote Site to the ISP is defined with the identifying name of “Internet”. The configured network service is PPP, our local WAN address and the remote router address will be dynamically learned when the connection is established. In addition, we will dynamically learn the addresses for two remote DNS Servers. The login name for this account is
Network Address Translation will be enabled, allowing all the workstations on our local LAN to share one public IP address. This Remote Site will be used as our default gateway. The ATM virtual channel is VPI 0 and VCI 32 and the Peak Cell Rate is set to the default access rate. This remote site is configured with the following commands:
add vc Internet
