specify a host to access the internet through an ISP-2 line

When ISP redundancy is configured in the primary/backup mode, is there a way to specify a host to access the internet through an ISP-2 line?

Someone told me that this method is impossible to achieve, is that correct?

Primary /backup means all traffic goes through ISP-1 unless it is down. If you want some traffic to go the other way, you need a different mode.

Yes. See sk42636 for more details.

Perhaps you misunderstood my meaning, SK42636 seems unable to solve my problem. Do you mean 'load sharing mode' can solve this problem?
My question is: The client can freely choose the ISP line to access the internet, and select the line by setting the host nat.

The question is not clear at all. If you want to provide internet access to a specific population of internal hosts through a specific provider, yes, it should be possible, through Load Sharing mode.  

On top of the SK I gave you already, look into sk32225. Which is referenced in SK42636, if you missed it.

If you want your internal users to choose a specific ISP link by themselves, then no, it is not possible.

Thank you very much for your patience.

I have read sk32225, which tells the story of certain traffic going out through the first ISP. I hope to set it up so that certain traffic can go out through the second ISP. Can it be set up like the attachment I uploaded, or in other ways, in load sharing mode?

Regards.
