Simple Routing help!

Wed Jun 12, 2013 4:00 pm

Hi,
Im guessing this is really simple, but cant get it to work. Please help!

I've been given 1 class c Ip Range by my ISP.
The Gateway provided by my ISP is:
GW:80.121.82.1
Ip Range: 80.121.82.0/24

When I set 80.121.82.2 on port 1 of my Mikrotik, I'm able to ping externally.
I have tried a whole mixture of settings on my PC and MT but im unable to route any traffic externally from behind the MT

I just need some basic pointers on a initial setup... Thanks in advance.

If the GW is inside of the subnet that you got assigned, you need to be in the same L2 segment, then assign an IP out of that subnet to your device, and use the GW and it will work.

Since the subnet is not routed to you, you cant use it inside of the network, only on the same L2 segment with the GW.

Or use smaller subnets in your local network.

Can you post an example?

Regarding the GW been on the same subnet, I was guessing this was an issue.
Would it be a good idea to see if the ISP can change the GW to allow me to route the complete class?
as layer 2 connectivity isn't going to be possible

Yes, just ask your ISP to route the subnet to you.

Then you can do whatever you want with it inside of your network.
Split it into smaller blocks and route those around, or assign IPs with PPP-like tunnels as /32s.
