hi all sifus here, i have a question. i just got a RB750. i want to setup it to be a router at my school's computer lab. now my school use maxis's vsat, which which are connected to a 24 ports switch. now every computer need to configure ip address before can connect to internet. now i want to make the rb750 to be a dhcp server, that'll give automatic ip to all pc connected to it. my setup will be vsat gateway => rb750 => 24ports switch =>pcs/ap/wireless routers. how to setup it? ive looked in the wiki and cant seem to find the answer.....i didnt know that mikrotik is very hard to configure...i bought it because my friend said its high quality......hope any sifu can point me to the right direction...tq..

How did the Maxis vsat device works? Is that a router by itself?
Assuming that the answer is yes, and that the Maxis STB has its own IP (for example 192.168.1.1).
Connect the decoder to port 1 of the RB750.
Connect the 24-port switch (I assume it is unmanaged) to port 2 of RB750.
Configure the port 1 of RB750 to have the IP of 192.168.1.2/24.
Make a srcnat masquerade NAT rule with port 1 being the Output Interface.
Create a DHCP server running on port 2 of RB750. If the said port is part of a bridge, run the DHCP server on the bridge. If a bridge exist, port 1 must not be part of it.
Configure the computers to use DHCP, and then connect them to the unmanaged switch.
At this time, the computers should be able to connect to the Internet already.
