I am trying to establish a site to site VPN from an Azure VM (running debian and strongswan) and a remote site. to clarify, The debian box is setup to establish an IPSec VPN with the remote site. I have created the appropriate endpoints to support this (ports 4500, 500...etc)
My configuration is working in another environment outside of azure. It seems Azure may be blocking this type of traffic in some way. I see requests being sent to the remote party, but a connection cannot negotiated/established.
Is this simply not supported or do I need to continue working on changing my configuration to get it working?
I understand that I can establish an Azure provided VPN, but I'd prefer not to do this if possible.
Thanks
