Port Forwarding on a Double NAT system
-
Hi guys. I'm current setting up a pfSense server on Proxmox VM, but I couldn't figure a way to open port to the internet.
Overview my network structure
ISP Modem
- WAN IP: dynamic
- LAN IP: 192.168.1.1
Host Machine (Running Proxmox)
As below
Guest Machine (PFSense)
- WAN IP: 192.168.1.102
- LAN IP: 10.0.1.1
I want to open a port on my Host Machine (for example: 10.0.1.2:10000)
At first I tried Port Forward both on ISP Modem and pfSense
On pfSense, I create forward rule from WAN:10000 -> 10.0.1.2:10000
On ISP Model, I create forward rule from WAN:10000 -> 192.168.1.102:10000 (I also tried to set 192.168.1.102 as DMZ IP)I used to solve a Double NAT problem like this before on TP Link router. But it didn't work on this case.
After googling a while, some people said that I should just disable NAT on pfSense (because for some reason I cannot change my ISP Modem to bridge mode). So I go ahead a disable NAT by choosing "Disable Outbound NAT rule generation. (No Outbound NAT rules)" on NAT > Outbound tab.
Then, tried to set Port Forward rule on ISP Modem with each rule below but no luck- WAN:10000 -> 192.168.1.102:10000
- WAN:10000 -> 10.0.1.2:10000
I did tried to debug by view States and Packet Capture then find: "10000" but I nothing was found
I'm pretty new to networking so if I did something wrong please tell me, also, if you need more debug log/information please let me know.
