Question:
When creating an inbound access list on a serial port connected to the Internet that is performing NAT (Serial is the NAT Outside interface), which IP address should be specified in permit statements, the internal Inside local (i.e 10.1.1.x) or the Inside global or public address of the translation?
For example:
access-list 105 permit tcp any eq 80 10.1.1.0 0.0.0.255
or
access-list 105 permit tcp any eq 80 xxx.xxx.xxx.0 0.0.0.255
(where xxx.xxx.xxx is the range of public ip addresses?)
Any help would be appreciated!!
