running simple NAT along with PCC

Have RB493AH running fine with PCC load balancing:
2 x PPPoE connections to one internet provider and LAN pool is 192.168.1.0/24.

What kind of problems may I have If a setup new local IP 10.100.1.0/24 to other unused ethernet port and setup simple NAT with one of the PPPoE as WAN port.
One of the PPPoE connections will be used with the both pools.

The configuration works, but I am not sure - if this is “allowed” ?

The setup is made just to separate some of the computers from the other.

Try it out but take first a backup from your config before.
You set the 10.100.1.0/24 and set it up as dhcp-server?
You can nat the interface with one from the PPPoE as WAN
Try like this, is an example but must work.
