Public IP without NAT over PPPoE Server

Tue Oct 12, 2010 3:38 pm

I want to configure this ip's on my PPPoE Server.
Followed addresses are given from my ISP:

- AAA.BBB.184.48 – AAA.BBB.184.63 Customer IPS

Net AAA.BBB.184.48 /28 are routed to:

Router Transfer net adresse:
IP-Adresse: AAA.BBB.173.203
Netzmaske: 255.255.255.192
Gateway: AAA.BBB.173.193

Can somebody help me with some lines of script to config this IPs??
Its urgent they want to change this config tomorrow.


The existing config is a running PPPoE Server with lokal IP's 172.16.0.X
and a pppoe-out dailup with one public ip ant nat.
and now i want to change this lokal ip's to public ip's.
And I'm not sure how I can do this.

Regards
Nobbe

You make an IP pool containing that customer IP range and assign it to the PPPoE server so that it hands addresses from that range to customers dialing in. Then you add the 'transfer address' and netmask to the interface facing the ISP and add a route for a destination of 0.0.0.0/0 (the /0 is important!) with a gateway IP address equal to the one given to you by the ISP.

Is it useful to create a example in the wiki-forum with that conifg ?
I saw a few questions with the same issue in the board.

Hi,

Can anyone show an example using a private IP range so I can test at home. I have been trying to get this working for some time now in our core with our public ranges but with no luck at all.

Cheers,

RW.

I had to apply proxy arp on both interfaces to get this working, does anyone know why?

Thanks,

RW.

Because your uplink doesn't have a route to the pool via your WAN - because you're using the network the pool is in ON your WAN link.

At least according to http://forum.mikrotik.com/viewtopic.php ... 16#p255916

Please don't double post. It duplicates efforts to help you.
Specific answers require specific questions. When in doubt, post the output of "/ip address print detail", "/ip route print detail", "/interface print detail", "/ip firewall export", and an accurate network diagram.
