Guest VM can not get IP via DHCP

[tfrist]

I installed Win7 VM.
It can not get the IP address from DHCP and connect to the internet, however, it works if I specify static IP for it, like 10.13.1.10.

I have set net_enable to 1 as blow in /etc/drakrun/config.ini.

;============================================================
[drakrun]
; if set, drakrun dumps raw VM guest memory after finished analysis with drakvuf
; compressed dumps are stored as "post_sample.raw_memdump.gz" in analysis folder
raw_memory_dump=0

; whether guest VMs should have access to the Internet or no
net_enable=1

; through which host interface the Internet traffic from guest VMs should be routed
out_interface=enp75s0f1

; the address of DNS server as reported to the guest VM by DHCP
; if you want to have a DNS on a gateway IP, use this setting:
; dns_server=use-gateway-address
dns_server=8.8.8.8

;============================================================

'drakrun@*' service has been also restarted after the modification.

xen@xenpc:~$ drak-healthcheck
Checking daemon status...
drak-web.service OK
drak-system.service OK
drak-minio.service OK
Checking worker status...
drakrun@1.service OK
drak-postprocess@1.service OK

On the Guest VM where, upon checking the network status, I can see it sends out many packets but does not receive any.

This problem has been persisting for several days, and despite my efforts of searching extensively and attempting various solutions, I have been unable to resolve it.

Could you please provide assistance with this issue? Let me know if you require any further information.

Thank you for your help.
