Hi,
I can't ping either way (VM to PVE or PVE to VM) through a NAT'ed interface. I've tried setting its interface to 'NAT Mode' & 'Bridge Mode' (using the bridge with NAT enabled), and either way I can't ping through the NAT. But PVE can ping the internet.
Here is my /etc/network/interfaces:
The VM in question is a multi-WAN gateway, & I can get it to work properly when I use the following /etc/network/interfaces:
When I use this configuration, I can set the Multi-WAN VM to get the static IP on the eth1 connection, & a DHCP supplied IP on eth2. Multi-WAN works on the LAN(s), but PVE can't get an internet connection itself, so I get no backup status emails, & it won't update with apt.
