Question ISPConfig with multiple ISPs - what's the correct way?

Hi, everyone!

I'm trying to get some redundancy with the connection for this ISPConfig server.
I'm not sure what is the best way to do it. I don't have AS numbers.
Is it possible to do it without AS numbers? Can I just use two NICs with static IPs?
Aside setting up the second IP in the ISPConfig, what should I setup?
I consider adding the second address in the DNS setup, e.g.:

www.domain1.tld 123.123.123.111 (ISP1 on eth1)
www.domain1.tld 213.213.213.222 (ISP2 on eth2)

The server has only one gateway set, through ISP1 on eth1.
Would it respond correctly to requests coming on eth2 ?

What's the easiest way of doing this?

I should mentoin that I also can request multiple IPs from both ISPs and use a multihomed router in front of the server, but without AS numbers, I'm not sure if this is a good idea (I'm thinking of setting up pfsense without NAT).

I would, actually, be content with modifying manually some settings, as long as I don't have to fiddle with DNS, as it would mean to wait for propagation, which is exactly what I'm trying to overcome.

Please shed some light on the correct path.

Thanks,

grasomega

Default

I think I will try to use a router in front of the server (with NAT) which accepts 2 WAN connections and setup the server with 2 IPs on the same physical interface with IPs on the same C class and setup SNAT from the ISP1 IP to the IP1 (on the server) and, respectively, SNAT from ISP2 IP to the IP2.
