Hello guys,
I have a ip 192.168.20.3 with default subnet and gateway is 192.168.20.1, dns 202.70.64.5. Now i have brought new MikrotikRouter 450G and i need to share it over new local network. How to configure my 450G MikrotikRouter??
Here is a good article about initial configuration: http://wiki.mikrotik.com/wiki/Manual:Initial_Configuration
You can also use Quickset for the most basic configuration: http://wiki.mikrotik.com/wiki/Manual:Quickset
i had tried but still it says gateway unreachable and if i ping google.com then it says no route to host… 
Have you configured you default gateway (default route) in /ip router section?
yes dst is subnet, gateway given by isp is in the gateway field
IP > Routes dst add 192.168.20.0/16 and gateway 192.168.20.1 and interface ether1…
this RB450G makes me cry.. ;(
default route 0.0.0.0/0 also added to the route list..
Route with dst. 192.168.20.0/16 will only route to your local network. Try using 0.0.0.0/0 instead.
yes now it works. actually it was problem of subnet.. i use CIDR but it was /16 network… 
thanks guys for support
what is CIDR ?
plz say some thing about this
