i am running opnsense as a virtual machine in proxmox

i have a additional ip 148.***.***.158 for WAN
and i have a subnet 136.***.***.224/29 for LAN

both are configured as static

the LAN ip is using the first ip of the subnet 136.***.***.224

so i am accesisng the gui using 136.***.***.224 on LAN

then i have enabled DHCP on LAN
with start 136.***.***.225 to end 136.***.***.230

so when i create a ubuntu desktop virtual machine i can obtain an ip from opnsense
and i can browse the web with the obtained ip inside ubuntu virtual machine

but the ubuntu cant be pinged from outside because firewall blocks it unless i disable the firewall

so there should be some rule to setup but i tried so many rules and nothing helped

i have a subnet 29 from hetzner

i am not running this on my local pc

if i use the private ip how am i supposed to serve my website to the public ?

can you be more specific pls

im not a expert

Hello, i dont understand
do i have to change my lan ip with one of those ips ?

How would i do that ?
any example

Hello, i have dhcp running o my lan

when i receive the ip adress (136.***.***.225) on a client i can access the intenet inside the client

but i have a problem i cant figure it out

i have a webserver running on port 9999
but the firewall is blocking it
if i disable the firewall temporarily i can access the port 9999

i tried many options in lan rules but nothing worked

how can i create a rule to allow access to port 9999 for the lan dhcp ip ?

Bump

Hello i have succesfully installed opnsense
i access the gui using LAN
and i have configured WAN and enabled DHCP

now the thing is my Wan subnet is not protected
for example if i create a windows RDP, its by default accessible
how can i create a rule for my leased ip so i can allow and block ports ?

i am very new to networking and stuff

Thank you soo much  :-*

Well, your LAN IP range is using public IP adresses, which is a baaaad idea, unless you own those addresses, which I doubt.

Are you sure youre using a correct subnet mask? I would recommend to compare the mask from your DHCP server with your manual IP setup.

Disabling WAN firewall... Are you serious?
I can only hope that on your WAN comes another LAN. In that case, you probably are blocking private IP adresses on the WAN interface and should disable that setting found under Interfaces / WAN.

i have a main ip for my proxmox
and then i have a subnet/29
first ip is using for opnsense static lan

i use the correct subnet theres nothing wrong with the subnet
like i said i dont use wan and there is no wan settings under interfaces as i dont have a wan

like i said again i disabled firewall because i had trouble setting it up so i disabled it for testing purpose

i use opnsense just for dhcp nothing else

Hello i have installed Opnsense on my dedicated proxmox server as a VM with only LAN

let say my static LAN ip is 192.130.246.8

and then i have setup DHCP, it works amazing and i love it

dhcp from 192.130.246.9 to 192.130.246.15

i also have a Windows 10 vm in my proxmox got my ip 192.130.246.9 from opnsense dhcp and the gateway is 192.130.246.8

now the problem is i could not setup the firewall rules for RDP i kept getting error "Default deny rule"
so i disabled the firewall for testing

now i can connect to rdp but sometimes the rdp desktop freezes and then after some time it gets back to normal
and then sometimes it freezes then i get connection closed

for linux server vm i have no problem accessing http/https

if i dont use opnsense dhcp and set my network in rdp manullay everying works smootly

this has to do with opnsene and i dont know why

does anyone has any clue ?

edit: okey finnaly fixed it after 24h or so

if anyone else faces the same issue using hetzner proxmox
let me know
