ASA 5505 DMZ clients can't connect to the Internet

tlitterio2
Level 1
Level 1

I have been wracking my brain for hours with this. I have tried allowing all ip from this interface but nothing seems to work. Can someone please review the below config and give me an idea of what I could be doing wrong?

Device Manager Version 6.2(1)

Thanks!!

You're missing NAT from the DMZ to the outside. Try adding

nat (dmz) 1 192.168.10.0 255.255.255.0
