QEMU with slirp is a simple client program. Virtual network in QEMU which
has DHCP server doesn't have any relationship with a host's network
configuration. If your debian can get an IP address like 10.0.2.x by dhcpcd
or dhclient from virtual DHCP server , the problem is that packets cannnot
be sent or received to QEMU.

If you can use tcpdump as root on a host OS, you can check it.
[host OS]# tcpdump -i eth0
or
[host OS]# tcpdump -i eth1     (if you have two cards)
or when you use a host-gest connection,
[host OS]# tcpdump -i lo

Then use a program on a guest OS.
[guest OS]$ lynx  http://----example-----/

When a connection is normal,  you will see some output of tcpdump.
