PIX 515 : Unable to access DMZ through VPN connection.

Here is my problem. I have a client based vpngroup named xxxxxxxxx.
This works great except that I can't access any of the machines I have
on my DMZ through the VPN. I have a feeling it's an access-list issue,
but for the life of me I can't seem to find it. Maybe my brain has
finally melted. Occupational hazard I guess.

I think I've included all of the necessary config commands.
Any help is greatly appreciated.

Oh yeah PIX version 6.3(1)

access-list 210 permit ip vvv.20.1.0 255.255.255.0 yyy.16.23.0

Are you using nat 0? What do you have for the dmz if you are? Use
separate acl for inside/dmz nat 0 as well, or you run the risk of
overlapping the two.

Post the enire config (change the public IPs to a.b.c.x and drop the
username/password) and I'll have a look.

Regards,

Scott.

Thanks Rik;
It was the nat 0 statement that I was missing on the DMZ interface. Dooh!
