Intrusion prevention whitelist openVPN Traffic?

[frust]

Hi all,
I'm trying to whitelist ssh connections from openVPN to a internal machine.
I can not get it to work. Always after 4 successfull connections I get blocked.
Simplified example:

$ for i in $(seq 1 5); do ssh xxxx@compute date; sleep 1; done
Mi 7. Jul 11:32:42 CEST 2021
Mi 7. Jul 11:32:43 CEST 2021
Mi 7. Jul 11:32:45 CEST 2021
Mi 7. Jul 11:32:47 CEST 2021
ssh: connect to host compute port 22: Connection refused

* First try was to set a bypass rule in network config

-- no success
* next I tried to IPS after other scans
-- no success
* finally I added a bypass rule to IPS

-- no success

I'm out of ideas. Can anybody help?

(EDIT: Forgot to mention UT version is 16.3.2)

Solution found

After a week of poking around I found a solution:

The variables section contains in "$HOME_NET" the entry "default". This does NOT include the OpenVPN network.
After setting this variable manually to the wanted networks it works as expected.

Why the general network-config bypass rule not works is a bit unclear to me. Maybe this is caused by the OpenVPN tun network device, what's possibly not reacting like a real physical network device.
