Dual WAN

[Pocah.H]

Just a quick question. I was considering updating my ISP service, which will require me to re-organize the ports on my router, an AX11000 Pro.

My question is, are Ethernet ports that are not assigned to any WAN allocated to the LAN?

The configuration I need is
10G Port -> WAN1
LAN1 Port -> WAN2
2.5G Port WAN -> LAN

But I am not sure that's possible because it would require the 2.5G port to assume that it's connected to the LAN rather than a WAN.

Perhaps instead it might be necessary to have

10G Port -> LAN
LAN1 Port -> WAN2
2.5G Port -> WAN1

That seems more likely because I think the 10G port does assume it's LAN unless otherwise configured?

What does the user configuration guide say about what each port can be assigned to ?

No idea. It isn't specifically mentioned in the configuration of the router and I can't find it in the manual, hence my question.
I mean I am guessing that the 10G port defaults to the LAN and only becomes WAN when it is selected in the router configuration as either the WAN1 or WAN2 port. But that's a guess.
As to what happens with the 2.5G WAN port, I am not at all sure, because it is specifically called a WAN port and indeed it is THE default WAN port. I don't know if it can be LAN if is not selected as WAN on any configuration page..

Don't know which router you are using, but beware of dual wan issues -

Thanks for the heads-up.

I have not checked the dual WAN since the update. It is a failover so it doesn't get tested often. I will follow this up in the thread you gave me.

I think the way the dual WAN is configured has changed. There are profiles now. Anyway....

Thank you, but I don't think that answers my question.
It's not how to configure the WAN(s). rather it's what happens to the ports that aren't configured as a WAN. Do they automatically become LAN ports?
Let me describe what I need. Maybe that's a better way.
I have 2Gbps WAN from my ISP. Also I have a 1Gbps service as a fail-over. And my home network is 2.5Gbps. So, I need 1x2.5Gbps port for the LAN, 1x2.5Gbps for WAN1 and 1x1Gbps for WAN2.
What's the best way of doing that?

I suspect that the 10G port will be LAN unless configured as WAN, but what really puzzles me is what about the 2.5G port? That is specifically called a WAN port, yet it is possible in the configuration to leave it un-selected as a functioning WAN port. Does that mean in the lack of configuration it will default to being a LAN port? Or will it just not function?

If you use the two ports marked for WAN service (DUAL with failover), you will only have Gigabit LAN from your router to your lan devices. Can one of the USB ports can be successfully used as a secondary WAN port with a USB ethernet adapter for failover ?
Basically, this router is short 1 port that can function at 2.5 Gbit/s or faster for your LAN use case if you use the Dual Wan assignment. The other 1 Gb/s LAN ports cannot be converted to a WAN port from what i can see.

If your LAN is through a 2.5Gbit/s switch for all local traffic, then a 1 Gbit/s uplink to the router probably won't hurt much and likely not noticeable.

Ah, right.
So, based on the wording of the information you supplied, I tried this configuration then -
ISP 1 connected to the 2.5G WAN port, ISP 2 connected to 1G LAN port 1 (which needs to be set to WAN 2 in the Dual WAN configuration), and my LAN connected to the 10G port, which was left unconfigured.
Success! That works. It does seem that unconfigured, the 10G port defaults to the LAN.
I didn't try using the 2.5G WAN port for the LAN. It's still possible it defaults to LAN if unconfigured, I just didn't check it because there is no point. By the time any of my ISP's offer a 10G service this router will be obsolete!

I have not actually tested the failover yet. I will do that now and report back to the other post.

 

[Pocah.H]

The failover works too.
The configuration changed, which is why I believe that people are confused as to why failover is not working any more. It is, they just need to change their configuration to include WAN indexing.
