We have around 80 odd sites with ipsec route based tunnels and some with agressive tunnels that have 4g or natted connection.
We have just added a nex SRX320 into the mix and it wont get phase1 with an agressive tunnel like all of our other SRX configs. If I change the mode back to mode main it works ok. Has there been any major changes with agressive tunnel configuration? Running SW version is 15.1X49-D75.5]
What concerns me is that these other 80 sites will soon be upgraded.
