WiFi may superficially look like Ethernet (i.e. have similarly looking MAC address), but it is actually not, so naive binding of XQ to host WiFi interface would not work for that reason.<br><br>In addition, guest operating system software using DEQNA/DELQA will likewise be expecting 802.3 structured frames and protocol capabilities.<br><br>Therefore, some form of translation between 802.3 and 802.11 or tunneling of 802.3 packets through 802.11 (or generic TCP/IP) would be required.<br><br>If all you want is to connect SIMH instance to exterior TCP/IP network via IP connectivity only (i.e. do not
need VAXcluster, LAT or DECnet), then regular host OS level bridging of tap interface (or Windows interface such as loopback or wired Ethernet interfaces) to WiFi interface would be one thing to try. Bridging is likely to suffice to translate IP packets from 802.3 MAC envelope to 802.11 and vice versa; that is it's purpose anyway.<br><br><span>If, on the other hand, you want to interconnect multiple SIMH instances over WiFi utilizing not only IP, but also other Ethernet based protocols such as VAXcluster or LAT or DECnet, host OS bridging may fail to translate those protocols. In the latter case you'd need to find a way to tunnel 802.3 packets over 802.11 or over generic TCP/IP. General approach would be to attach SIMH XQ to Linux tap device on one side and hook tap/tun's other side into tunneling software. VDE (<a target="_blank" href="http://wiki.virtualsquare.org/wiki/index.php/VDE">http://wiki.virtualsquare.org/wiki/index.php/VDE</a>) does just
that, but I personally do not have experience using VDE. Furthermore, there is some direct VDE support in the latest version of SIMH (assuming the simulator executable is built with VDE option enabled). I have not personally tried using it, but at a glance at the code, it looks like it allows to connect XQ to VDE_SWITCH directly (using vde:port syntax), not requiring tap device as an intermediary.</span></div></body></html>
