I just got the UDM Pro and got to setting up the Site-to-Site VPN. Everything seems to work, but I'm unable to add all 3 redundant subnets that I've got set up in my AWS VPC.
It works fine with a one, but after adding another one, the first one breaks while the second one works.
Does anyone have experience with setting this up? What am I doing wrong?
This is how my current config looks like:
AWS Subnets -
eu-central-1a - 172.31.16.0/20
eu-central-1b - 172.31.32.0/20
eu-central-1c - 172.31.0.0/20
UDM Pro - Site-to-Site Subnet Section
