[fuse-emulator-devel] W5100 emulation in Fuse

[Andrea <mar...@gm...>]

I see FUSE has a W5100 Ethernet card emulation

https://sourceforge.net/p/fuse-emulator/fuse/ci/master/tree/peripherals/nic/w5100_socket.c

I am writing an emulation for this card for AppleWin (Uthernet 2).

I have a POC and was trying to understand if I could use the one from fuse.
I noticed the following difference:

fuse emulates udp and tcp, while I need ipraw and macraw.

So I did my homework and got them working.
But I then hit a few issues and wanted to understand how you solved them

- raw sockets require privileged access (annoying)
- impossible to forward udp packets for dhcp (root or no root).

The problem with udp packets is that I need to listen on port 67-udp and this is impossible because 
it is already taken by dnsmasqd on my system.

So this is the question I have for you: have you got any example of a ZX80 software that does DHCP 
and this works with your W5100 emulation?
If yes, I am really curious to see how you did it.

I have a solution, but it is a huge effort, where I intercept DHCP, reply wit a dummy (10.0.0.1) and 
then forward udp and tcp packets (a la NAT)
I think this is what VirtualBox does.

Thanks
