If it was just the host, I'd suspect the firewall.

Are you using all the options at once?
I'm using "-net tap,ifname=qemu-7eggert -net nic" on Linux to do this.
You should also get a NATed network using "-net user -net nic".
I did not yet use the -net bridge option.
My network bridge is set up like this:
iface br0 inet static
bridge_ports eth0 qemu-7eggert
bridge_maxwait 0
address 192.168.x.210
netmask 255.255.255.0
gateway 192.168.x.y
pre-up tunctl -t qemu-7eggert -u 7eggert
Unfortunatwely I only get one tap device, but I want to avoid everybody to
have network pernissions. Maybe there is a nice way to have a virtual
switch per user? (shamelessly mentioning my own "problem")
