Overlapping subnets

[Jhonata]

Hi everyone,

I am having an issue with two different incoming services on a cisco ASA. We have 2 different applications that are connected to the ASA, the first one is an Tunnel 10.1.0.0 / 16, and the other is a direct connection to our network with subnet 10.1.0.0/17, they are in different ports, they are overlapping and everything is routed back thought the tunnel, there is any way to solve this issue? I tried NAT but only works internally, onece it gets to the r

What you meaning via tunnel ?

You mean there is static route toward tunnel? Or it is IP of tunnel itself?

It is routed through the tunnel

Then using NAT must work I think' but there is note as I remember' you can not use VTI interface in NAT you need to use ANY instead

Where should I apply the NAT, on the first source?

Source 1 : 10.0.0.0 /17

Source 2 : 10.0.0.0/16

Tunnel 10.1.0.0 / 16 <- this need NAT

Not direct connect.
