HI,
I have been wondering around the forum for the past few days and I still cannot figure out what I need to achieve what I want .
I appreciate if anyone can just point the direction where I should go.
The scenario is:
Mikrotik AP with pppoe server up.
Client connects via wireless with senao cb3
Senao is connected to the linksys befsr41 router/gtw.
Behind the linksys router/gtw there are 10 computers.
I need to authenticate the client for billing purposes and and the same time to provide Public IPs to his Lan network.
I tried that by putting pppoe authentication on the linksys router and I have the following problems.
First if I turn off the nat option on the linksys router the lan port can ping the wan port of the router but nothing else so no traffic nothing comes out of the router.
Second if I put on the nat option on the router I have traffic/internet on the computers but all of them come out with single IP address the one given to the wan port by the pppoe server.
So by looking over the forum I found different answers but none of them kind of are providing me the answer to what I should do.
Again I appreciate any help, any direction to what I should do. Is 1:1 NAT a solution , arp-proxy, is it at all possible what I want to do , any answer will help.
You’re going to have to pppoe each client computer behind the Linksys BEFSR41 and pppoe the Linksys as well.
You have to use the Linksys in router mode - not gateway mode, i.e. Linksys LAN IP 10.1.23.0/28 (useable addresses are 10.1.23.1 through 15, .0 is network, .16 is broadcast). Set gateway of computers to the Linksys Lan port address.
Linksys WAN port public or private address, for example 172.1.1.18/30, Gateway would be 172.1.1.17, network would be 172.1.1.16, and broadcast would be 172.1.1.19
Senao cb3 - you didn’t say if this unit was bridging or routed so I left that part alone.
So it would look like this;
Client 10.1.23.5 <>Linksys LAN 10.1.23.1 <>Linksys WAN 172.1.1.18<> Senao cb3 (bridge mode or routed)<> MT AP w/pppoe
Either the Senao or the MT AP would have to have the address 172.1.1.16 in the above example.
I think it’s up to the customer to sort out port forwarding for his own internal network. You can supply a Public IP behind NAT from your MT AP to the customer by using proxy-arp and he can have it asigned to his Linksys WAN by PPoE. All he/she has to do is to setup port forwading on their Linksys as you would normally with almost any broadband service. If you want more elaborate routing for the customer side I think you should get a better router than Linksys!
