I have two questions, and will appreciate a quick response.
I have a VPN 3030 connected on a DMZ Interface via public address. We put the VPN 3030 behind PIX for added security.
1) What kind of address translation do I need to allow VPN users coming from PIX outside interface to the inside network via DMZ interface.
2) How do I allow IPSEC and HTTPS traffic to be allowed via PIX. Note: VPN 3030 is the actual box where all the IPSEC configuration will take place. PIX just has to allow it.
Can someone shed some light on it.
See below the config as well.

1) There are several ways to accomplish this task. The easiest way to accomplish this is to use the static command like this:
static (dmz,outside) 1.2.3.4 1.2.3.4
**where 1.2.3.4 is the address you have assigned to the public interface on the 3030
2) Add the following lines:
access-list ACL-IN permit udp any host 1.2.3.4 eq 500
access-list ACL-IN permit esp any host 1.2.3.4
access-list ACL-IN permit tcp any host 1.2.3.4 eq 443
**again, where 1.2.3.4 is the address assigned to the public interface on the 3030
Hope this helps.
