allow access from internal device to another internal device
-
Hello, I have the following network layout: PFSense > Server > Proxmox > VM's
I am trying to allow internal VM to communicate with another VM for email servers and other servers via domain names.
Example: I have a VM for a forums, I want it to be able to use mail.domainname.com to communicate with the Email VM on the same proxmox/pfsense installation network
Does anyone have any tutorials or instructions on how to setup i think 1:1 nat to enable this? If its not 1:1 nat what is it? Sorry i am new to nat stuff.
Any help would be awesome, Thanks.

You need both
-
Ethernet level 2 connection. This is most easily done by having them on the same LAN. Within Proxmox that is done most easily by having them on the same bridge (the virtual equivalent of a physical Ethernet switch)
-
IP routing (if you intend to use a WAN IP to access a local LAN device). Look at NAT reflection
