NAT Cloud DHCP Issue - EVE PRO 6.2.0-20

Post by anon_strider » Wed Feb 19, 2025 7:25 pm

Hello,

I came across an issue since upgrading EVE PRO to 6.2.0-20. Connecting any device to the NAT cloud network does not acquire a dhcp lease. I can see the discover packets egressing the router but nothing in return. No modifications have been made to the EVE server. I do not see any dhcp server service running either. please help.

EVE-NG: VM running on ESXi host


EVE config for nat interface in /etc/network/interfaces:
# nat device
auto natmac
iface natmac inet manual
pre-up ip link add natmac address 00:01:01:01:01:01 type dummy

auto nat0
iface nat0 inet static
bridge_ports natmac
bridge_stp off
address 172.29.129.254
netmask 255.255.255.0
postup ip link set nat0 address 00:aa:aa:aa:aa:aa



Topology:
VPC Connected directly to NAT Cloud

VPCS> ip dhcp
DDD
Can't find dhcp server

For all -

Rusty assisted and uncovered that the udhcpd service is not properly associating the nat0 interface upon initial bootup.

The workaround for now is to run 'systemctl restart udhcpd'
