Advanced Routing

[Guest_imported]

I have faced the following problem :
I have an OBSD 2.9 box which is a Router. It has 3 NICS. The first is connected to the ISP1, the second to ISP2 and the third to my LAN. On the other hand in my LAN I have to subnets: 192.168.1.0/24 and 192.168.2.0/24. The computers in these nets have a Default Gateway th OBSD box.

I want to let the first network through ISP1 and the second through ISP2. The real problem is that I have no idea how to do this ?!?!?!?

net2=192.168.2.0/24

Any comments ??

Well, I would connect the two networks on two different cards, themselves ,connected to two different physical networks.

Hi.

I believe you will need a fourth(4th) NIC on the OBSD box so that the two internal LAN segments can route to their own gateway.

192.168.1.1 |

net1 |

192.168.2.1

net2

Default gateways for each internal LAN segment will be:
net1 = 192.168.1.1
net2 = 192.168.2.1

OpenBSD will be the router between the two LAN segments. From there, you can also define how you'd like to route each LAN to the internet. ---
