Hi!
I have just learned how to setup DHCP Server on MIKROTIK thanks to this forum. Now i want to learn how can i setup my Internet GATEWAY on Mikrotik.
I dont want to use the UID and PASS feature, just want to allow particular IP’s with their respective MAC Addresses to use INTERNET through this GATEWAY. For now i dont want to setup any proxy server one thing at a time 
that i will learn later on.
I have shifted my DHCP Server to MIKROITK and its working fine. Now i want to shift my Main GATEWAY to Mikrotik.
Looking Forward for some Help.

To make Mikrotik as a Intenet Gateway. you should have ateast following
Mikrotik with Atleast 2 ethernet.
Configuration
IP Address -
192.168.1.2/24–> ether1 (We assum that this is a Internet IP Provided by the ISP)
10.10.10.1/24–> ether2 (Your Local LAN IP)
Ip Route
You shoud have one defalut Route
/ip route
add dst-address=0.0.0.0/0 gateway=192.168.1.1—>ISP End
Than you have to NAT you local network with the INTERNAT
/ip firewall nat
add chain=src-nat
src-address=10.10.10.0/24
action=masqureade
Also add DNS entry
/ip dns
set primary-dns=X.X.X.X secondary-dns=X.X.X.X allow-remote-request=yes
Thats..It
Please refer Mikrotik Documents as well as Visit http://wiki.mikrotik.com for examples
Add me in MSN for any further help
you only need two things:
- Ip/Mac binding which is achieved like this:
- a. add IP/Mac combinations to the IP ARP menu
b. set your interface to “arp=reply-only”
- Masquerading (if you use private network IPs)
- a. add new SRC-NAT rule with Out-inteface=public and Action=masquerade
