Will try to explain :
Current network …
dominantly windows clients on DSL WAN connection
Several mobile clients ( phone / tablet )
Mediaplayers ( PC-based )
All glued together via several GBswitches ( unmanaged )
one dedicated VPN server ( open-wrt router ) - connecting to office network ( uses DSL-WAN )
machines connected to this VPN-router need the external (wan) IPadres from the office-server to connect to the 'professional services )
What I want to create :
(have) DSL-Modem just that, telephone & WAN modem
(need) Mikrotik device ( open for suggestions - liking the CRS125 or RB2011UiAS )
I would like to see predefined devices routed by the Mikrotik based on IP or MACadress to VPN or ‘open’ WAN
for example :
PC1,PC2 Android1 → WAN ( direct IP )
Laptop1, Phone1 & 2, tablet1 → VPN ( connected to office-wan )
New clients → direct to WAN
Is it possible by rules, or even connect defined devices via vlanXX to WAN and vlanXY to VPN
( I’m hoping it all makes sense, had to translate an idea to english 
)
