RouterOS Beginner Basics
1

Hi to all..
Im new at all this so I need plenty of help..

I Have RB450 ROS 3.25..
The thing is..
There are two offices (in two difrent citys) which has to bee connected with a VPN connection with IPsec.

at office one there is the rb450 which should be connected to an optic modem at port1
at port2 should be the server
at port 3 pc from my boss
at port4 AP
at port5 VoIP

at the other office, there is no mikrotik router, just a siemens se515 router..

so, i’m in the office where the siemens router is and i have to connect remotly to the mikrptik in the other city..
i don’t even know how to do this..

can somebody help me to configure this??
