This makes all the machines on the local network (network 0 from now on) appear as if they are connected to the main network (network 1).</P ><P >This is only relevent if all machines are connected by Ethernet or ether devices (ie. it won't work for SLIP/PPP/CSLIP etc.)</P ><P ></P ></DIV ></DIV ><HR></DIV ><DIV CLASS="TOC" ><DL ><DT ><B >Table of Contents</B ></DT ><DT >1. <A HREF="intro.html" >Acknowledgements</A ></DT ><DT >2. <A HREF="why.html" >Why use Proxy ARP with subnetting?</A ></DT ><DT >3. <A HREF="how.html" >How Proxy ARP with subnetting works</A ></DT ><DT >4. <A HREF="setup.html" >Setting up Proxy ARP with subnetting</A ></DT ><DT >5. <A HREF="alternatives.html" >Other alternatives to Proxy ARP with subnetting</A ></DT ><DT >6. <A HREF="applications.html" >Other Applications of Proxy ARP with subnetting</A ></DT ><DT >7. <A HREF="copying.html" >Copying conditions</A ></DT ></DL ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" > </TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="intro.html" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" > </TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Acknowledgements</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
