Map and forwarding problem

Tauer Drumond — Mon, 11 Mar 2019 13:50:00 GMT

Hi,

I've created a static NAT:

static (inside,outside) 200.200.200.10 172.16.0.10 netmask 255.255.255.255

It's working fine.

But, now I want to forward all traffic to destination 200.200.200.10 port 8888 for 172.16.0.20 port 80... and I'm putting the command:

static (inside,outside) tcp 200.200.200.10 8888 172.10.31.20 80 netmask 255.255.255.255, and the ASA is showing me the following error:

ERROR: mapped-address conflict with existing static

inside:172.16.0.10 to outside:200.200.200.10

What should be the better way to resolve this problem?

Thanks

Tauer

200.200.200.10 ip address is completely being used 172.16.0.10 .so its dedicated and we cannot use it.

you can use it in Dynamic NAT

nat(inside) 2 0.0.0.0

global (outside) 2 200.200.200.10

and then use

static (inside,outside) tcp 200.200.200.10 8888 172.10.31.20 80 netmask 255.255.255.255

Sorry,

I tell you the wrong IP.

Instead 172.10.31.20, you consider 172.16.0.20

Anyway,

should I replace the line you wrote:

nat(inside) 2 0.0.0.0 to

nat(inside) 2 172.16.0.20

Thanks
