Having issues with Azure IPSec Connection
-
I managed to get my tunnel setup and a wopping 412bits of data sent over the connection but I realized that my local range was offset. My LAN is 192.168.71.0/24, and Azure was set to 192.168.70.0/24.
I jumped into the config and changed the local range from Network(192.168.70.0/24) to Lan subnet, saved and disabled / enabled the connection. I also updated the config on the Local Connection in Azure to point to my local LAN range of 192.168.71.0/24. Its now been stuck on 'Connecting' for an hour with no data.
Any ideas as to what I am doing wrong.

I just posed about an issue with ipsec not updating... ssh to your pfsense box and see if /var/etc/ipsec/ipsec.conf is updating. I saw the same messages in our logs when the end point was trying to connect to our pfsense box.
You may be having the same issue.

Based on what the other side is presenting I would probably select AES 256 and SHA256.
