Router/Switch after Firewall

[ISSM]

Hello,

My current setup that's working is ISP > Firewall (DHCP Server/NAT/ACL) > Switch > Computers.

I want to put a Router between the Firewall and Switch even though I know it's not needed, but we paid for it.

Firewall "Inside" > Router's G0/0/0 and G0/0/1 to Switch.  Router and Switch are open with no configuration.

All computers gets an IP address, but no access to the internet.  On router, I did an ip route 0.0.0.0 0.0.0.0 192.160.0.1 (Firewall Gateway IP).

What am I doing wrong?

So I got the DHCP server working on the router and my clients gets an ip address from 192.168.1.0/24.  However, no internet access.  I think I have an issue with routing between Cisco FTDand Router.

Our windows server (DC/DNS) is on another subnet...192.168.0.0/25.  Is this an issue?

I have attached the Router/FTD running config.

nat (inside,outside) source dynamic any-ipv4 interface
nat (inside,inside) source dynamic any-ipv4 Router_to_firewall

it not DNS issue it NATing 
you here only NAT the subnet between FTD and router 
you need to add object-group for LAN subnet and then add dynamic NAT under it 

[ISSM]

So I added an object-group for LAN subnet (192.168.1.0/24).  What would be the original and translated packets for source/destination address?

Would this be nat (inside,outside) source dynamic Lan Subnet interface?

LAN subnet is 192.168.1.0 or 192.168

0.0 ??

[ISSM]

192.168.1.0

[MHM Cisco World]

Go head add 192.168.1.0 object group and config NAT 

Interface will be (inside,outside)

Hello @ISSM,

On your FTD, based on the conf of your post [‎05-23-2023 06:43 AM]

[route inside 0.0.0.0 0.0.0.0 192.168.1.1 10]

is not [route inside 0.0.0.0 0.0.0.0 192.168.0.2 10] ?
