Cisco ASA Site to Site VPN using DHCP for outside interface?

Tags: Cisco, ASA 5505, ASA 5505
We have been using the Cisco ASA 5505 to connect one of our sites using a linksys VPN router just fine for the last 4 months(DES, MD5, group1).  I recently have been trying to add another site to this ASA 5505 with no luck.  The new site is also running an ASA 5505 with 3DES, SHA, group 2.  The new site's outside interface uses DHCP to obtain is IP address.  The ISP assures me that it is reserved and does not change.  Can a vpn be setup using DHCP on the outside interface?  The encryption is chose on the new site is 3DES while the existing vpn uses DES.  Is this a problem?  I am using Cisco ASA 8.0.3 and ADSM 6.0.3 to configure.  I am familiar with the command line so if you know a fix please let me know.   I have reloaded both sides multiple times but still no luck.  I even did a factory default force and started over and still no luck.  Any help would be appreciated.  I will try to post the running-config later.

Also,  after I create the connection profile it doesn't seem to connect according to the debug log.  Is there a set of commands to force the VPN connection to attempt to connect?  Let me know.

Thanks
