Setting up Cisco VPN with NAT to remote network

So I'm trying to setup a Cisco ASA 5505 for VPN to a remote network and I need to NAT my internal IP address based on their requirements.

Here are their instructions:

Their hosts:
192.168.50.83 (Surescripts Host Server)
192.168.50.85 (RxHub Host Server)
192.168.50.86 (Surescripts Host Server)
192.168.50.50 (Patient Portal Host Server)

Remote Peer IP: 66.179.80.108
Remote Network: 192.168.50.0/24 (255.255.255.0)
Your Local Network: 10.x.x.45/32 (255.255.255.255)

Clinic will need to make ACL from 10.x.x.45/32 to remote network 192.168.50.0/24

Clinic will need to NAT interesting traffic to 10.x.x.45/32 (255.255.255.255)

I have a lot of experience with Linux IPtables and IPchains, Open source firewalls like M0n0wall (monowall) etc., but not sure how to do this with Cisco.

Will spend some time figuring this out...

Any help is immensely appreciated!

Wolfram | Alpha Search Engine

Watch out, there's a new search engine in town...

The search engine that will be going live in the next few weeks:

http://www.wolframalpha.com/index.html

Instead of you typing in words and it finds pages with those words, you type in something like "Population in Illinois" and instead of returning pages with that text, it actually calculates the predicted answer of your query and returns graphs/charts/comparisons.

Or you type in "Salary in LA compared to NY" and it will return the comparison with charts and everything...

If this actually works when it goes live, it could be way better than google is at the moment... But for now, google obviously pwns the market of delivering relevant pages on the web...
