One wan, 2 public subnets. How to configure?

[bruor]

I've got an internet connection coming my way from a tier 1 provider but they're using a configuration that's got me a little confused when it comes to implementation.

They've provided me 2 public address ranges,  one is a /30 that I am to use for my router,  the other is a /27 that are the public IPs to use for services.

Will pfSense automatically understand what's happening if I just add virtual IPs to the wan interface for the entire /27 range?  I'm hoping it'll see traffic for that IP hitting it on the /30 address and just handle it.  I'm in the process of building an environment to test this now but if someone else can confirm I'd be grateful!

My suggestion is to assign the /30 on wan and /27 on a dmz interface.

Thanks.

I went ahead and threw a VM on the wan subnet and tested hitting IP aliases that belonged to another /27 and it worked without issue.
