IPsec GUI allows creating multiple identical Phase 1 entries when using FQDN for remote gateway
Moving from internal Redmine issue 6010 since this affects CE and Plus and isn't hardware-dependent.
This is a new behavior that I've not seen until recently (after upgrading to 21.02).
I was creating a p1 for a user, and when 'apply change', it hung there for about 2-3 minutes (the device has 30+ tunnels), eventually resulting in a 504 gateway timeout error.
Then I logged into the device again, and clicked apply changes.
When I looked the tunnels to see if they were created, I noticed identical p1 tunnels created.
Normally, pfSense would error out if I created multiple identical tunnels.
I tried to create another identical p1, and I was successful.
It seems like you can create as many as you want.
From the notes:
Was able to reproduce it using the remote FQDN gateways
That PR has already been merged and picked back to 21.05
