Subnet to Subnet NAT

Dor_Marcovitch — Tue, 19 Oct 2021 10:18:22 GMT

hey,

i have a problem with overlapping networks in S2S connections.

we currently have the configuration currently on our cisco that it performs destination nat based on "network to network" for example:

192.168.1.x -> 10.10.1.x

that way we do not need to configure 100 NAT rules, and the cisco router know to perform NAT for example:

we have multi[le subnets like this,

thanks

And what is the issue here ? You only mention a Cisco device (and not even which one)...

we need to remove this cisco device and move the S2S to be between the 3rd party to our checkpoint GW.

it some cisco router i dont know the model

But what is the problem you are facing ? You can define these NAT rules on CP easily ! I suggest to read sk108600: VPN Site-to-Site with 3rd party

I believe what you are looking for is NAT Pools

The NAT Rule base let you easily define such configuration - look into Dashboard...
