I have FreeIPA setup on CentOS 7 in AWS. However we are looking to lock down communication over our VPN tunnel. Trying to do some research to see what ports I need. I've gotten most of them, 80,443,88,464,389,636,123. I have it setup to allow UDP/TCP for both sides. However in the amazon security groups I have found that if I remove 0.0.0.0/0 from the inbound I lose communication to the remote FreeIPA servers. However the server in AWS can talk back.
This email thread might not be relevant here but I wanted to see what kind of response i'd get.
Are there ports similar to what needs to be opened for AD ?
I found this on Amazon's website:
Thanks,
Andrew
