ASA 5505 Can't telnet in from outside to NAT address
This seems to look right to me, but here is the config of a ASA 5505 and I can't telnet in to the NAT address 192.168.1.13 .. the packet trace says blocked by implicit ACL, like the main address-list ACL is not even there... It looks like several others I have setup, but here they only have the outside interface to map too, only that one open IP address @ .34 ... maybe that is the problem... anyway here is the config:
