Here is the download page, you can select 19.4. I'll upload the version here so you can check checksum since you only use it for upgrade.
Downloads (juniper.net)

Here is the latest
Junos Software Versions - Suggested Releases to Consider and Evaluate (juniper.net)


The latest suggested is 21.4 now.
Thank you very much for this and the guidance..

There were a couple of big CVE's this year in the SRX world - make sure you're running latest recommended - and good call to check hashes against the official download sites..

As long as you don't expose web admin page to internet you are fine. Basically limit remote management to local IPs.

So just so that everyone is aware - I am having issues with Destination Nat when on 21.4R3-S3.4 - I have a fully working DNAT setup that worked just fine on 21.2R3-S3.5 that broke when I 'upgraded' to 21.4R3-S3.4. In fact it affected 2 setups. The same configuration started working again when I 'downgraded' to 21.2.

If any has a working config of DNAT on 21.4 please let me know - I can try that again. But in the meantime those having DNAT - be aware that installing 21.4 will break it. Going to try 23.1 next to see how that goes.

I am looking for 12.3X-D10 for the SRX3600. I have not been able to find it online. Does anyone have a copy or know of a link to download it from?
Thanks.
