hi,
it should work with routed interfaces.... things to check:
-if the ubuntu client can ping the 192,168.0.1?
-if the ubuntu client can ping the 10.0.2.15?
-if freerouter installed the default route: sho ipv4 rou inet
-if the client can ping the freerouter's default gw? (from the above output)
br,
cs

Hi all,

Question:

I decided to test a different DHCP Server topology on FreeRouter.

Topology (VMs):

* RARE/freeRtr - Debian 11
* 2 Clients - Ubuntu 21.04

The network configuration, defined a NAT (WAN) to Internet and a Internal
network (LAN).
I got the client to receive the DHCP IP on the FreeRouter, but it is without
external connectivity.
I wanted to know if it is necessary to configure a routing policy for the
Ethernet1 interface or is a bridge perhaps needed to perform such a routing
function?

Gateway: 192.168.0.1 (Internal network - Interface Ethernet2).
Objective: Fetch connectivity via 10.0.2.15 (NAT - Ethernet1 interface).

Configuration Server DHCP freeRtr:

!
server dhcp4 dhcp-server
pool 192.168.0.2 192.168.0.100
gateway 192.168.0.1
netmask 255.255.255.0
no dns-server
domain-name
interface ethernet2
vrf inet
exit
!

I need my DHCP to receive external connectivity, more details from the
question on github:
