Hi, bit of a strange request, i have a piece of software that wont talk to 2 units if they are sharing the same vpn mainly because the softeware is rubbish but were stuck with it 
At the office side we have a draytek router, and on the site we have a RB450
Is it possible to have a vpn connection for each port so port 2 (1 will be the link to the boradband) it has vpn 1 which links to the draytek, port 3 has vpn 2 which dials to the draytek.
Is this possible? and if so how i’ve been looking for the past 2 hours and have no idea how to do it
Many thanks
