Network via intel 350t4v2 - please help

[guest15389]

I'm trying to follow that diagram and I can't figure out what you are trying to accomplish.

Do you have 2 internet provides and that's what provider means? Are you looking to do multi WAN with a port for each provider?

Are you trying to add in multiple LAN connections for redundancy?

If you spend some time and make an accurate diagram, it will really help as without a picture it doesn't make sense (to me anyway).

Do you have 2 internet provides and that's what provider means? Are you looking to do multi WAN with a port for each provider?

Yes.

Are you trying to add in multiple LAN connections for redundancy?

No.
2 WAN (OPT1, OPT2) is used for one service provider and another.
2 LAN (OPT3, OPT4) are used to distribute traffic from one service provider and another.

2 WAN (OPT1, OPT2) in two intel 350 t4v2 and 2 LAN ports (OPT3, OPT4) in the other two intel 350 t4v2 ports

That is, you need to drive traffic through intel 350t4v2.
Built-in network interfaces in the motherboard do not touch
The standard LAN that is integrated into the motherboard will be used for synchronization.

Everything is simple

Normally, you'd use a multi wan setup to provide redundancy and give your capacity an increase. You aren't normally setting up a multi wan to route one link into point a and another link into point b.

It sounds like you want a single WAN to point a LAN port and basically have another WAN and point that to a LAN port.

Again, this is where a detailed picture would really help to show what you are trying to achieve.

Link to the picture.
It seems that everything is clear. Or not?

I have fixed the reference to the scheme in the first post

A similar problem is observed in pfsense.
But there the configuration on intel 350t4v2 is executed immediately, that is, the WAN and LAN are configured there and everything works out of the box.
But if you manually configure LAN on intel350t4v2 yourself, then there will be a similar problem.

So two servers, two WANs? Are you using CARP and standby HA? Because it would solve your issues.

Looks to me the OP tries to do that in one box.

[franco]

Sure but ideally one box actively manages both WANs while the other one doesn't. Or both boxes manage one WAN, then you can leave out CARP but need a third device to do gateway group load balancing.

I agree. That makes sense for a failover setup.
