I have the following situation that I cannot make heads or tails of...
ip nat pool XYZ 10.1.0.50 10.16.0.200 netmask 255.255.240.0
ip nat inside source list 1 pool XYZ
access-list 1 permit ip 10.0.0.0 0.255.255.255 192.168.1.0 0.0.0.255
access-list 1 permit ip 10.0.0.0 0.255.255.255 192.168.100.0 0.0.0.255
access-list 1 permit 192.168.161.0 0.255.255.255 192.168.100.0 0.0.0.255
access-list 1 permit 192.168.161.0 0.255.255.255 192.168.1.0 0.0.0.255
....
....
My problem is understanding what the second subnets in the access-list entries signify. I have only seen NAT access-lists with ONE subnet for each entry. Any help is appreciated. Thanks.
