Hello,
I'm trying to set up DHCP with the following parameters:
- New Branch Router should provide DHCP addresses for both R&D and Admin PC’s.
- Exclude the first 500 addresses for R&D
- Exclude the first 100 addresses for Admin
But the request always fails. I can't figure out what I'm doing wrong. Any help is appreciated!
Here is my Topo:
Here are my configs:
| New Branch |

I'm also going to post a compressed file with the packet tracer and the current configs I have.
Thanks in advance!
