Multiple PPPoE with the same gateway

Decker

(Sorry for my english ;) I need to estabilish 2 PPPoE connections (2 pppoe sessions) to my internet provider and set up load balancing. But they have same gateway ip (for example, pppoe0 uses login - user0, dynamic wan ip and gateway ip - 10.50.254.197, pppoe1 uses login - user1, dynamic wan ip and gateway ip - 10.50.254.197 too). pppoe0 connection runs normally, but i have problems with pppoe1 connection, it can't start. Screenshots of two connections and ifconfig you can see in Russian Support forum - http://forum.pfsense.org/index.php/topic,28245.msg147055.html#msg147055 .

I think that the problem in the same gateway (Sep 13 03:24:32 ppp: [opt1] 212.106.34.109 -> 10.50.254.197
Sep 13 03:24:32 ppp: [opt1] IFACE: Adding IPv4 address to pppoe1 failed: File exists) and in the routing tables. For both connections I have same gateway. How to establish two ADSL connections with same gateway?

This is not possible.
You need a device in front of the pfSense which does NAT for one of your WANs.
Since you write that these are ADSL lines, i suppose you can configure one of your modems to NAT traffic for you.

This is not possible in current version (2.0 beta) or this is impossible at all?

I understand that i can set up one of the connection in my ADSL modem, for example pppoe0 is set up in modem and through modem NAT it comes to pfSense as DHCP interface (for example), and second connection (pppoe1) is configured by pfSense directly (i.e. in modem we have one pppoe and one bridge). But if i have more than two connections? I want to setup a some kind of gateway for torrent downloading with multipath routing / load balancing … for two connections (one in modem and one in pfSense, WAN1 = DHCP, WAN2 = PPPoE) i've already done this (each connection / account have 5 Mbps incoming speed shaped by my provider, for two - i have 5 + 5 = 10 Mbps with load balancing, it's already work for me) ... But i have another one account ... and wanna set up 3 connections ... and want 15 Mbps download speed from internet with my ADSL2+ ... ) Can i do this without another router?

GruensFroeschli

It is currently impossible with any version of pfSense.

If you have more than 2 modem it should not be a problem.
Just configure the modem to NAT traffic.

Sorry to jump on this thread but I have a similar question. I am planning to deploy pf to run my wifi network. I have 3 wan connections for loadbalancing and redundancy. I will use captive portal and user manager as well.

WAN:
2 DSL lines and 1 cable isp. DSL connections are PPPOE.

LAN: Switch connected to LAN port. WIFI access points (ubiquiti) connected to the switch.

Are you saying that I can only do one PPPOE connection from pf?
so my WAN setup can only work as follows:

pppoe directly from pf
PPPOE on modem/router and NAT to PF
cable ISP to PF

GruensFroeschli

Yes.

With 2.0 you will have the option to terminate all the PPPoE connections on the pfSense.
However the limitation that no two WANs can have the same gateway still applies.
