How can I map SSH from an outside network range to an internal host (ASA 5505)

Question

Cisco Adaptive Security Appliance Software Version 7.2(4)
Device Manager Version 5.2(4)
- External network range that needs SSH access: 8.8.8.0/24
- Outside interface: 10.1.10.2 (NAT'd from 7.7.7.7)
- Inside Network: 192.168.100.0/24
- Inside host to redirect external SSH to: 192.168.100.98
Hi All,
I have a Cisco ASA 5505 (version above) and I have someone that needs to SSH into a box behind the ASA. I'm having a few issues trying to configure this access-list and NAT. I've tried many combinations and clearly my IOS is not as good as I thought.
Can anyone help with this? What commands should I enter to accomplish mapping SSH from an outside network range to an internal host?
Many thanks,
Tarran

This may or may not work depending on how your modem handles the natting. On your firewall try this -
static (inside,outside) tcp interface 22 192.168.100.98 22
then add this to your acl on the outside interface of your ASA -
access-list outside_in permit tcp 8.8.8.0 255.255.255.0 host 10.1.10.2 eq 22
if you don't have an acl applied then add this extra step -
access-group outside_in in interface outside
