Since the Cisco default is to have a proxy ID for the range being matched for interesting traffic and the Juniper side had been set up with host-by-host proxy IDs, I put a range proxy ID on the Juniper and it all worked just fine.

TIL that Juniper and Cisco VPNs define proxy-ids differently.

TI also L that, among other things, proxy-ids have to match for a VPN to work.
They work differently for practically every vendor. Very annoying.

It depends on the number of subnets you need to cover, but for SRX to ASA/CheckPoint/whatever I tend to go with policy-based by default and manually specify the proxy ID as configured in the security policy. If it's a simple one with just one subnet on each end, a route based usually works fine though, but I still put in manual ProxyIDS  :whistle: 

However, SRX to SRX sets it to 0.0.0.0/0 which is odd again.

root@Branch-vSRX-01> show security ipsec security-associations index 131074 | match Ident
  Local Identity: ipv4_subnet(any:0,[0..7]=0.0.0.0/0)
  Remote Identity: ipv4_subnet(any:0,[0..7]=0.0.0.0/0)


When an IPsec request comes in and it's a different vendor:

Wow really?  This made me go look in a certain vendor config guide to verify it was there ;)

Love the haikus.

TIL that WMI error 0x80041003 is a show-stopper for CounterACT NAC only if we don't deploy the client.

And we're deploying the client.

TIL that for an FTP operation to be successful, the FTP server needs to be running the FTP service. :doh:  :wall:

Thing is, I'd been going around and around with a backup operator for the last few months on getting this backup job set up, but my device would never connect to the FTP server, at all.

And then the different guy I get from the backup group today to help out says, "Hmm... none of those servers you were working with are running FTP."

And then I was all like...
:phone:

He got me an IP address of an actual FTP server and everything went like a champ.
