Connecting an AWS pfsense appliance to multiple AWS subnets

Dandm001 · Jul 5, 2016, 3:40 PM

I have successfully set up a number of pfSense hardware appliances in AWS, each connecting to a single subnet with the VPC and then established an IPSec VPN to a remote site.

However, now I need to do the same but for a VPC that has multiple subnets. The VPC has a /24 CIDR, with the subnets within the VPC being /27's.

I have tried setting the encryption domain to be the /24, but cannot get it to work. I have also tried setting multiple p2's (one of each subnet), but cannot get that to work either.

Can anyone tell me how I need to configure the pfSense appliance?

The remote firewall in each case will be a Check Point.
