Errrr.... According to the interfaces status and the routing table,
this is the
case, or do I misunderstand your question ?
The traceroute you showed was going out the default gateway. I guess
that was a workstation on just one subnet.
Lets start with the obvious, you have
sysctl -a net.inet.ip.forwarding
set to one right ?

OK, you see MAC addresses from the other devices and they seem to be
on the correct interfaces. you can ping them right ? They all have
you as the default gateway ?
e.g. if you do
ping -S 102.168.0.251 192.168.0.254
ping -S 10.75.2.251 192.168.0.254
do both work ? Does 192.168.0.254 have 192.168.0.251 as the default gateway ?

No, there is no "trunk" ports. The term trunk is used by Nortel for MLT. And,
precisely, that what's "show mac-address-table" displays : the MLT table. The
port I'm connected to is simply a port shared by all Vlans.
OK, but the port will tag all the packets leaving it with the correct
vlan right ? Some switches offer a "hybrid" mode were the packets all
exit the port untagged. But based on your arp table, this does not
seem to be the case which is good.
