Load balancing and inbound traffic

[dmaldonado]

Hello, 

I'm curious to know how many people handle inbound traffic when two WAN links are used on the MX. My understanding is that load balancing is primarily for outbound wan traffic but wanted to be sure. 

Thank you,

Load balancing does apply to outbound requests, but the inbound reply comes back on the same circuit - so, in effect both inbound and outbound end up getting spread across both Internet circuits.

Forgive my ignorance here. If your request is coming in, do you not have to choose what WAN IP address you’re  wanting to hit for whichever resources at home base you’re trying to access? For example, if youre trying to access something remotely you would presumably be pointing to one WAN IP. If that link is down, there is nothing to auto resolve that attempt to use the second link.

In this scenario you just point your request to the IP on the secondary WAN. Or you let your DNS-server handle a rewrite of the A-record if the first circuit goes down.
