OK guys

i need some help on this,

OK here it goes, i have a house with 2 clients on the premises the one client wants 1meg PPPoE the other wants a 4 Meg PPPoE and they want to use VOIP also PPPoE..

On the 750 I have..
1: Ethernet 1 links up to a Air Grid M5 in Bridge mode
2: Ethernet 2 setup for client 1 ( DHCP)
3: Ethernet 3 setup for client 2 ( DHCP )
4: Ethernet 4 setup for Voip ( DHCP )

I have setup PPPoE Dial-up
1: PPPoE Dial-up for client 1
2: PPPoE Dial-up for client 2
3: PPPoE Dial-up for Voip

For some reason I can get the Nat and the routing to work, each client must go out on his own PPPoE Dial-up .

we have also set up on Radius Manager 4 that..
client 1 gets a ip address 10.1.0.198
client 2 gets a ip address 10.3.0.188
Voip gets a ip address 10.5.0.120

Can some-one Please help

You could try the following setup:
IP->Firewall:

  • In the “Mangle” tab add 3 rules to the prerouting chain to mark the outgoing packets based on the incoming interface with 3 different routing marks.
  • In the NAT tab add masquerade rules for each PPPoE outgoing interface with the corresponding routing mark set according to the ones in the first step
  • In the Filter tab, add 6 forwarding rules, 2 from/to each interface pairs (incoming and outgoing, you don’t need to use the marks here)

I use this setup with 2 PPPoE interfaces and it works without problems.

Of course you must also set up the default routes in the IP->route tab so each connection with the proper routing mark has a different default route.
