Our network uses VPNs and VLANs.  

I have one device in VLAN 10 (192.168.10.x range), but when you login over the VPN, we put you in VLAN 12 (192.168.12.x range).

I want to make it so when I come in on the VPN, I can hit that one device in VLAN10.  I think I need to add a static route, just not sure were....on the PIX?

It is always a good idea to add static routes in the pix for vpn clients.

for your vlan 10:
pix(config)#route inside 192.168.10.0 [subnet mask of this network]  [inside interface of pix ip address]
pix(config)#route inside 192.168.12.0 [subnet mask of this network]  [inside interface of pix ip address]

Also, your router or layer 3 switch on your inside lan should have either static routes with the above networks pointing to the inside of interface of the pix or a dynamic routing protocol such as eigrp, rip, or ospf to find all your vlans so traffic can go to all your default gateways of your vlans

I have those routes, but I think this is the relevant VPN stuff:

access-list 101 permit ip 192.168.12.0 255.255.255.0 192.168.2.0 255.255.255.0


When you VPN in, we give you a 192.168.2.x address.  So we are saying, once you have that 2 addy, you can go anywhere in 12 land.
What I want to say is "You can go anywhere in 10 land, PLUS you can also go to 192.168.12.39".

How would I do that?

Thanks.

In the original post you wanted 1 server in VLAN10, now you want 1 in VLAN12 - did you confuse them?
I'll go general since I'm uncertain of the specifics you want :)

You don't tell what access-list 101 is applied to, or what other access-lists are relevant (You aren't reusing 1 for several purposes, right? *shame on you if you do*)
Are you using split-tunnel?  If you are, you need to add this extra host to that.  In either case you'd likely require NAT-exemption, and then you add this host to that.

So from the limited bit you have shown, yes you extend the access-list (provided it's ALL VLAN12 & 1 VLAN10):
access-list 101 permit ip host 192.168.10.39 192.168.2.0 255.255.255.0

But the security of it is likely right down to missing translations now.  And of cuz, if the server can be accessed with shell/rdp you can jump on further into VLAN10.
