Traffic between subnets

[Henry]

I have a basic 192.168.1.x LAN:
Proxmox @ 192.168.1.1
IPCop GW & DNS @ 192.168.1.254

Proxmox has two bridges
vmbr0 = 192.168.1.1/24 GW @ 192.168.1.254
vmbr1 => DHCP @ broadband modem

My physical W/S @ 192.168.1.101

I am undertaking some study and an exercise requires me to setup a router VM with three NICs being:
1) External @ DHCP/Static
2) Internal @ 192.168.60.1
3) Internal @ 192.168.200.1

I have setup all three interfaces to use vmbr0

I think I should assign 192.168.1.249 to the Ext interface and use 192.168.1.254 for GW & DNS

I am unsure of how I can allow my W/S @ 192.168.1.101 to communicate with the VM server @ 192.168.60.1

The 192.168.60.1 server has a web interface that I need to be able to browse to from my W/S

Depends on which effect you want to have, but rather not I guess

1) External @ DHCP/Static => vmbr0
2) Internal @ 192.168.60.1 => vmbr0 (use the same structure as 192.168.1-0/24 but with another address)
3) Internal @ 192.168.200.1 => vmbr2 (with no physical NIC connected for communication between VM and their routing)

I think I should assign 192.168.1.249 to the Ext interface and use 192.168.1.254 for GW & DNS
I am unsure of how I can allow my W/S @ 192.168.1.101 to communicate with the VM server @ 192.168.60.1
The 192.168.60.1 server has a web interface that I need to be able to browse to from my W/S

Assign then e.g. 192.168.60.249 as second IP address in your W/S.
