Assing domain name to client vm

[prx]

Hi,
I can't figure out how to assign a domain name to a client vm.
What I need to do is to redirect traffic on the appropriate vm according to the 
domain name.

i.e.


                             +--MY SERVER VM'S--+
                             |                  |
         -------> foo.tld -------> foo          |
INTERNET -------> bar.tld -------> bar          |
         -------> els.tld -------> els          |          
                             |                  |     
                             +------------------+

So far, I have this not-working setup:

```/etc/vm.conf:
# something like in FAQ
switch "my_switch" {
interface veb0
}

vm "foo" {
    memory 512M
    disable
    disk /var/vms/foo.qcow2
    owner me
    interface { switch "my_switch" }
}
```

As specified in FAQ, I added veb0 and vport0 interfaces:
```
# cat << END > /etc/hostname.vport0
inet 10.0.0.1 255.255.255.0
up
# cat << END > /etc/hostname.veb0
add vport0
up
END
# sh /etc/netstart vport0
```

My vm has the address 10.0.0.2 and can ping its gateway 10.0.0.1.

ip forwarding is enabled:

```/etc/sysctl.conf
net.inet.ip.forwarding=1
```

Now I'm trying to use a binat-to rule in pf.conf, but I must miss something 
here:

```
int_if = "vport0"
ext_if = "egress"

match on $ext_if from 10.0.0.2 to any binat-to foo.tld

match out on $int_if from any to 10.0.0.2 \
        received-on $ext_if nat-to $int_if

pass on $int_if
pass on $ext_if
```

Do you have any advice to realize such task, maybe in a more clever way?

Regards.
