Can't connect FGT (ver:6.0.5) to FAZ (ver: 6.2.1 FortiAnalyzer), connectivity test fails;

FGT been added to FAZ devices;

exec log fortianalyzer test-connectivity Failed to get FAZ's status. SSL error. (-3)

Capture shows that FAZ sending RST back to FGT:

Any idea? 

Thank you for your input and help!

Hi guys,  looking for your support with FG 5.6.12 connecting to FAZ v6.4.6

FAZ:

config system global set adom-mode advanced set adom-status enable set daylightsavetime disable set hostname "xxxxx" set latitude "0" set log-forward-cache-size 4 set longitude "180" set oftp-ssl-protocol tlsv1.0 set ssl-protocol tlsv1.2 tlsv1.1 tlsv1.0 set timezone 89 set webservice-proto tlsv1.2 tlsv1.1 tlsv1.0

FG:

config log fortianalyzer setting set status enable set ips-archive enable set server "10.12.0.100" set enc-algorithm low set conn-timeout 10 set monitor-keepalive-period 5 set monitor-failure-retry-period 5 set certificate '' set source-ip "172.20.1.12" set upload-option realtime set reliable disable

When testing:

execute log fortianalyzer test-connectivity Failed to get FAZ's status. Authentication Failed. (-19)

In FAZ there is no "unauthorized devices". Tried to reboot the FAZ and different enc/oftp settings - no luck. 

In debug mode I noticed this error:

2021-07-17 19:03:57 [__SSL_info_callback:296] SSL negotiation finished successfully [ protocol : (771) TLS 1.2 ] 2021-07-17 19:03:57 [find_add_logdev:1941 FGxxxxxx] Warn Couldn't register DVM device due to can not register this device, error code -1002

and no clue what is code -1002 means - google did not help.

Has anyone met with such issue ?

ping and tcp-514 are running well, no blocks.

Thank you, works like a charm :)

This saved me a whole lot of time. Thanks genar! This works well in virtualbox and gns3.

It works on my VM workstation lab too. All VMs were using free perm trial license.

FAZ v7.2.1

FTG v7.2.3

I can even disable reliable connection (set reliable disable) on FortiGate.

Thank you genar. The Fortigate official admin guide don't talk about it and even the technic tip. The best I found official is this https://community.fortinet.com/t5/FortiGate/Technical-Tip-Connectivity-issue-between-FortiGate-and/t...

Genar, Thank you so much

I changed some lines based on your code and it worked

[stupid-dumb-idiot]

thank u!!!

[ichasovshik]

Thank yo Frosty!

Do you recall what was the command on FGT?

this is my current settings:

FortiGate-VM64 # get log fortianalyzer setting status : enable ips-archive : enable server : 172.16.x.x enc-algorithm : low ssl-min-proto-version: default conn-timeout : 10 monitor-keepalive-period: 5 monitor-failure-retry-period: 5 certificate : source-ip : upload-option : realtime reliable : enable

How to make sure that Encryption is enabled?

Thank you!
