Installing LEDE on QEMU (x64 / Debian)

Hi. I am interested in getting QEMU running on my x86 router running debian. It has 2 network ports. I have it running now purely on debian using IPTABLES. I think I can piece together what needs to be done from ( ) and (;a=blob;f=scripts/qemustart;hb=HEAD ), but if anyone has a good guide or any advice to contribute, I'm all ears. I'm particularly interested what iptables setup would be needed. I think I can adapt the above linked script, but I would need to know what services I might be running that I might need to disable (I would assume the ISC DHCP should be disabled, so I can do it in LEDE).
