Hi,

We use Mikrotik as router, gateway and firewall for internal subnet.
Inside we use Small Business Server 2008 (SBS2008) with built in DHCP, DNS ... and VPN connection for remote users from outside. For this PPTP I create dst-nat for port 1723.

In future we open 2 branch offices (A and B). I want all traffice from A and B go outside to internet through HQ (because stand-alone protocol/anti-spam cacher).

To create Point-to-point between branches MT and HQ MT i need port 1723 who I already dst-nat for SBS2008 functionality.
Plus for connection between A and HQ I need pppoe.
What sugestions to create Secure tunnel between A and HQ and B and HQ

Mocha
p.s. exchuse about my bad english.

Before dst-nat rule add accept rule where destination is B and source is A (or vice versa, depending which is the server). That way connection from another office is not dst-natted.
