HS/FS Send IP/EIB telegrams

[rburgering]

When I send a HTTP-request with the program Wfetch (sends RAW data to an IP-device) to a device, this device will response by sending his MAC-adress which belongs to the specified IP. When Wfetch gets this information (reply) back, it sends the HTTP request to the IP-device and receive again a reply of this device (acknowledge). This is the suspected behaviour.
When I send an IP/EIB telegram with the Gira HomeServer to the same IP-device, he sends the same request to the IP-device as the Wfetch program by requesting his MAC which belongs to the IP-address. In this case the device is not responding to the HS and the therefor the HS won't send the next message to the IP-device.
Does anyone know what went wrong by sending the telegram with the HS?

I have put some screenpictures for understanding the question, picture 1 is of the Wfetch and picture 2 is the request sends by the HS.

Small kick

If the question is not clear enough, please ask me. The reply may in german if you like.

Kind regards

What you see in front is an ARP request, solvin the problem of not knowing the MAC-Adress of a device in your own local network. However each system maintains an ARP table, and if this table already contains an entry for the destiantion IP, the ARP request is no longer required and thats why you might not see another ARP from the HS. IMHO normal behaviour.

However your connection is TCP with HTTP as the higher layer. What method are you using in the Homeserver?
