Hi All,
I have devices on our inside LAN (10.0.0.0/24) that are hardcoded to speak to an IP address: 1.1.1.1. Now 1.1.1.1 is being decomissioned, and I want to ensure that when our internal hosts route attempt to route to 1.1.1.1 they are forwarded to 2.2.2.2 instead (NAT adjusts the destination address).
ip nat outside source static 2.2.2.2 1.1.1.1
I believe the above does it.
But, I also need to ensure that the internal hosts (10.0.0.0/24) are natted to a public address (3.3.3.3) on the same router the above NAT is happening.
So for example when 10.0.0.0/24 route to 1.1.1.1, I want to change the source IP to 3.3.3.3 and change destnation to 2.2.2.2.
When 10.0.0.0/24 sends to anywhere else, just make source IP 3.3.3.3.
ip access-list standard NATPOOL
permit 10.0.0.0 0.0.0.255
ip nat pool NATPOOL 3.3.3.3 3.3.3.3 netmask 255.255.255.0
ip nat inside source list NATPOOL pool NATPOOL overload
THe issue is when I want to specify the source address as 10.0.0.0/24 going to 1.1.1.1 it doesnt apppear to be getting NATed and the routing is failing.
ip nat pool NATPOOL-2 2.2.2.2 2.2.2.2 netmask 255.255.255.0
ip nat outside source route-map RMAP pool NATPOOL-2
ip access-list extended NAT
permit ip 10.0.0.0 0.0.0.255 host 1.1.1.1
route-map RMAP permit 10
match ip address NAT
Can someone assist on the above?
