What about installing a KVM switch and administering the Debian computer
from the console?
If the two computers are separated, you could use a KVM extender and put
the KVM switch near the Windows computer. Or, you could get networked
KVM equipment.
That said, using one computer as router, firewall, file server, name
server, web server, and more represents "all of your eggs in one
basket". I suggest using dedicated hardware for networking, network
segmentation (e.g. DMZ), and kernel or hypervisor compartmentalization
of services. Qubes looks very appealing:
