Hi all,
Can someone see the problem? I am having two issues.
1) Ssh fails to the WAN of my 1711 NAT router. Can you see anything wrong with my acl's that would prevent this?
2) I can only get a response from some web servers on a dmz I created. I get zero response from others. I used 2 ports on the builtin switch and created a new vlan3.

Change your access-list 1 to:
access-list 1 permit 192.168.1.0 0.0.0.255
And see what happens.
