Ok, I have to ask. I have read every where for routing of Public Ip addresses and havent found what Im looking for.
I have a T1 and a Class C set of public IP’s. I have the T1, with the IP address assigned to me for that router, hooked in to my SBE card and configured and can access it. Now I want to take the Class C Static Public IP addresses and assign them to my clients after my MT router. I just cant seem to get traffic to pass or work correctly thru the router. In comming works fine but out going is a different story. Any one else doing this? Would appriciate direction.

Check the routing tables on the clients.. Sounds like they dont have the right gateway set. Usually you’d use the first available IP address in your /24 or whatever subnet they gave you as your core router’s IP address. This should have a default route to your PPP connection.
If you use DHCP make sure you have the network parameters set. If you’re using static addressing make sure you have the right gateway subnet and DNS.
Its all pretty basic.
Is there any examples of this for 2.9? I have been use to 2.8 and the new term is making me second guess myself. I think that I may have to use terminal mode instead of winbox. I dont understand why my gateways show blank.
Consider the following addresses (substitute your own):
Your assigned serial interface IP: 172.16.1.9/30
Your assigned default gateway: 172.16.1.8
Your public allocated IP block: 10.1.1.1/27 (10.1.1.1 - 10.1.1.30 usable)
A private internal block for NAT (optional): 192.168.1.1/24
Your interfaces:
SBE T1: sbe1
First Ethernet: ether1
Second Ethernet: ether2
/ip address add address=172.16.1.9/30 interface=sbe1
/ip address add address=10.1.1.1/27 interface=ether1
/ip route add gateway=172.16.1.8
(if you want internal NATed addresses too - or a new net on ether2)
/ip address add address=192.168.1.1/24 int=ether1
/ip dns add primary=
/ip dns add secondary=
Now, you can assign clients with public addresses. For example, add a client with the following:
IP: 10.1.1.10
Subnetmask: 255.255.255.224
gateway=10.1.1.1
If you want private NATed addresses, add the 192 rule from above, then add a firewall rule for your src-nat with a src-address=192.168.1.0/24 action=masq.
Hope this helps. If you still can get it working, you might have a problem with your T1 config.
