This documentation will show how it works with Windows and the PC/Flexnet package. First of all get your radio hardware running with PC/Flexnet which can be obtained at http://www.afthd.tu-darmstadt.de/~flexnet. Then add the virtual IP-adapter with Start -> Settings -> Control Panel -> Add Hardware. Choose "Yes, I have already connected the hardware" and click "Next". {{radio:db0fhn:ipoverwiz1.png|}} Choose "Add a new hardware device" and click "Next". {{radio:db0fhn:ipoverwiz2.png|}} Choose "Install the hardware that I manually select from a list (Advanced)". {{radio:db0fhn:ipoverwiz3.png|}} Choose "Network adapters" and click "Next". {{radio:db0fhn:ipoverwiz4.png|}} Click on "Have disk". {{radio:db0fhn:ipoverwiz5.png|}} Locate "ipover.inf" in subdirectory "IP W2k_XP" of your PC/Flexnet installdirectory and press "Open" ("ipax.inf" in "IP W9x" for Windows95/98/ME). {{radio:db0fhn:ipoverwiz6.png|}} Press "OK" and "Next". {{radio:db0fhn:ipoverwiz7.png|}} {{radio:db0fhn:ipoverwiz8.png|}} Press "Next" and "Continoue Anyway". {{radio:db0fhn:ipoverwiz9.png|}} Now you finished installtation of the TCP/IP over AX.25 adapter. Now start "Network Connections" from the Control Panel and doubleclick your new Local Area Connection with Device Name "IPOVER Network Adapter". {{radio:db0fhn:ipoverconf1.png|}} Click "Properties" and choose "Properties" for the "Internet Protocol (TCP/IP)". {{radio:db0fhn:ipoverconf2.png|}} Choose option "Use the following IP address" and insert a random IP-number out of the testing pool 44.128.x.y/16 (x,y = 1-254). Pres "OK" and "Close". {{radio:db0fhn:ipoverconf3.png|}} Now start your PC/Flexnet Control Center and Press "Tools -> IP-Routes". You will be asked for IP to AX.25 - Parameters. Enter your callsign with default SSID -10 for IP-over-AX.25 and check "Send UDP in VC" (ICMP and UDP will be send in connected mode). If this window will not appear choose "Edit -> Mycall/Parameters" in IP routes. {{radio:db0fhn:ipflexconf1.png|}} Now set the default route to use with "Edit -> Default route". In most cases it is the best way to use IGATE as AX.25 call and your local digipeater as "via". IGATE supports VJ-header compression so you can choose option "Virtual Circuit with TCP compression" and press "OK". {{radio:db0fhn:ipflexconf2.png|}} Now open the Trace window from the Flexnet Control Center with "Tools -> Trace" and a DOS box with "Start -> Run... -> cmd". Type "ping 44.130.60.100" and have a look on the Trace window. The connection should be established and ICMP-Echo requests should be send out and replyed. Further a new route will be added automatically in IP-Routes. {{radio:db0fhn:ipflexconf3.png|}} Congrats. Now you can reach TCP/IP-services of DB0FHN and others. E.g. you can type "http://44.130.60.100" into your webbrowser and get the mainpage of DB0FHN.
