Hi Group I am really ready to pull the hair out of my head. :)
For 3 months or so, I have had a VPN between my PA-200 to a PA-500 at my remote office. All was working fine.
Last night I come back into the office to find the VPN down, and not sure why. I am looking at my PA-200 which has exact configuration.
I can see via my pcaps that I am attempting to transmit my IPSEC traffic via agressive mode from my PA-200 to my destination PA-500 FW.
On my PA-500, I look in the system logs, and am seeing countless of messages "failed starting phase1"
Ok, I re-did my entire configuration on the PA-500, deleted old config, commit, created new config, and then commit.
Still getting failed starting phase1 I need to understand WHY is happening.
I do not have any insight or log to determine why it is failing to start. My PA-200 has dynamic IP, so I know my local PA-200 which be initiating the tunnel.
Looking at my traffic logs, and filtering on the public IP of my PA-200, I am not seeing any matching traffic.
No changes to my policy, but now, I am starting to open my firewall open in hopes to catch some sort of inbound traffic.
I could use some insight on this.
Well, I have no idea, but because I am playing in a lab, I just deleted all my rules and started over. The VPN tunnel is now back up with a smaller subset the exact rules. This is the 5th time I have seen a perfectly working VPN configuration just stop working and by putting in a different policy, it just magically works. I think there is something to be investigated in this 5.0.2 to 5.0.4 software......
Have you filed this as a bug to the support?
I have seen some threads aswell in this forum regarding VPN issues which seems to be fixed when you recreate the VPN settings.
One of the issues I think was when the order of where the VPN settings are placed within the running-config file was changed between two releases.
Is it possible for you to do a diff between the faulting config and the config which now works? Im thinking of if some naming standards has been changed which wasnt pickedup by the conversation scripts (which I assume exists when you go from one version into another?).
