I was cautioned by many about security concerns about doing this.
I didn't mention in my original post that this would have been for a
"practice LAN" that would exist within our LAN.
But the bottom line is that I was told by many that this would not work

thanks for the timely replies,
Here is my original Post:
I got a sparc ultra 5 running vers. 8 solaris.
I have it hooked into an HP switch along with the rest of our LAN.
I got the switch configured to have 2 VLAN's(a public and a private).
I have the sparc on both VLANs.
I want to use this sparc as a firewall to the boxes on the private VLAN.
The sparc in question has only one ether interface with 2 logical interfaces.
One interface for each VLAN.
hme0: is on the 198.107 (public) subnet
hme0:1 is on the 10.0 (private) subnet.
I am able to ping boxes on the public subnet, but not the private.
I have Ip forwarding turned on and have removed the /etc/defaultrouter file.
I did a route add net 22.214.171.124 and a route add net 10.0.0.0 through
each logical interface.
Still no luck. Can only ping to the public subnet.
Not sure what is wrong.
Should I NOT be attempting this with only 1 physical interface?
Even though I have it configured to be 2 logical interfaces with different
