I have an external IP 176.x.x.188 that needs to accept multiple external connections and forward traffic to 192.168.100.9 on a port range 10500 - 10600, having trouble making it work.
So something like:
Object network obj-176.x.x.188
Object network obj-192.168.100.9
Object network rng-10500.600
range 10500 10600
nat (inside,outside) source static obj-192.168.100.9
access-list outside_in permit tcp any host obj-176.x.x.188 range rng-10500.600
