I've not had any luck with this. I have an ASA with a sub-interface to a switch and from the switch I have a VLAN where a router sits to our remote office. It is not a VPN just a lease line via serial.
My LAN is on 192.168.3.0/24 and the remote network is 10.100.0.32/27
When 192.168.3.0 connects to 10.100.0.32/27 I want the 192.168.3.0/24 range to change to 192.168.90.0/24
I have attached my basic ASA config, to try and get this NAT to work I added:
access-list Inside_nat0_outbound extended permit ip 192.168.90.0 255.255.255.0 10.100.0.32 255.255.255.224
access-list policy-nat extended permit ip 192.168.3.0 255.255.255.0 10.100.0.32 255.255.255.224
static (inside,outside) 192.168.90.0 access-list policy-nat
Shoudl this of worked? I can ping 10.100.0.61 but it is still seeing me come from 192.168.3.0/24
