NICS on NAS routing traffic

hi all,

im very interested in getting a QNAP TS-231P as it has dual NICS but couple of questions before i buy

im going to install on it PLEX and a VPN eg torguard/nordvpn/hide my ***

i want to bind PLEX on NIC 1 and bind the VPN on NIC 2

basically if i want to access PLEX from the LAN/WAN i want it go in/out via NIC 1 and i want the VPN to use NIC 2 only

obviously the reason why i want to use seperate NICS for different things is because as soon as i start the vpn client it will get a random IP address from a VPN server and it wont get my ISP IP and when i want to access PLEX from outside i want it to use my ISP IP

is this possible?

many thanks,

rob
