Ethernet Gateway W5100 vs ENC28J60 in combination with signing

[TheoL]

I recently build a ethernet gateway with a W5100. It works like a charm but the sketch is large. When I setup signing on the gateway is just too large and it won't upload to the Arduino.

My thought was that I might be because of the soft SPI. Has anyone build an ethernet gateway with the ENC28J60 and signing? Will that sketch be small enough for the Arduino?

Also has anyone experience with an MQTT gateway and Domoticz? Is it easy to add new nodes to Domoticz with an MQTT gateway? I'm asking this, because the MQTT Gateway is much smaller than the ethernet gateway. I could be using this wthi signing, but I don't know what problems I'll be facing.

Thanx in advance.

I think ENC28J60 requires more flash space than W5100. Also, there seem to be a lot of problems with ENC28J60.
This thread had a similar discussion, it might help:

@mfalkvidd I'll dig into that post this weekend. Thanx for sharing.

I was wondering of a more powerful arduino, like the mega or due, can be used to build an ethernet gateway?

Yes, that is a good solution if you need more flash space. if you don't know already, there is a nice comparison table at https://www.arduino.cc/en/Products/Compare

@mfalkvidd thank you for the link. I found an Arduino mega for around 13 euro. It's worth to try that.
