When to use Multi-WAN?
«

I could not find a scenario chart of when Multi-WAN is useful. My goal is to get as much redundancy as possible.
My question is basically if I should use Multi-WAN. Would it benefit me with the following setup?
First of I want to state that I did try to set up a failover Multi-Wan configuration following the online documentation to the letter. It was not successful as I had many stalled internet accesses. I removed it.
This OPNsense box has 2 WAN's. The business Internet has a 100/20MB Mbps static IP (WAN1), and the other a 1000/50MB Mbps dhcp residential connection (WAN2).
WAN1 is used for incoming SMTP and business websites.
WAN2 is for residential internet, IMAP and SMTP outgoing, IPsec VPN to a local server, FTP, RSYNC, and video streaming server because of it's faster connection. WAN 2 also uses Dynamic DNS
I basically just use WAN1 for ports not allowed by my ISP residential service.
Now the big question. Is Multi-WAN an option for this scenario? Seems to me I have set IP's to do most connections, so I assume failover can't handle that.
I am also having LTE failover installed in a few day on WAN1. That is external to OPNsense.
Your thoughts?

No one?
Not asking for how to set it up. Just want to know if Multi-WAN is a viable option with my configuration.

Hi,
When you have 2 or more Wan, multi-wan is usefull for load balancing and when you have an access down

Hey,
in my opinion there is no need for setting up a dual wan.
If i get it right, you are hosting a Mailserver - connected to WAN1. If this is the case, i would not recommend a dual wan setup. Because your mails could be marked as spam.
Even there could be a problem with youd SSL certificate on your website. (which is also hosted on WAN1)
I f you are not using a Mail server or webserver ob your site, you can create a ruleset for Ports and bind them on one gateway.
Maybe you can explan, what exactly is hosted behind "WAN1"?
Thanks a lot

you could but ithink, what you describe is a bit to complex, for a dual wan. you need a lot of rules but for basic internet access for generic connection or HTTP... dual wan would generally work for your case.
(you need to setup the rules for you bussiness wan and residential wan to be allowed redirected first before going for the last dualwan gateway
