No Network in jail

[Sepphod]

Hello

I am a bit desperate. I've been trying for several weeks (excluding xmas vacations) to create a jail for a Gitea. This was working before that freenas 11.2. I am not happy at all with the UI but hey ok my server is headless and I can survive with it.
But the DHCP option is not working :( => so static IP address. But I am not able to see any ethernet interface with in my test jail :(.
So I tried to install the Jenkins plugin => this works. I don't know why.

I hope anybody of you can give me hint. probably it is just an layer 8 issue.

thx

That looks perfectly normal... and you say it's working... so where is the problem here?

The epair interface is bridged on the host to re0 (both members of bridge0), so this is how traffic is getting out of the jail.

Nothing to fix as far as I see.

first of all thx but from the console out of the jail I don't get a ping to my default route 192.168.178.1

Code:

Edit /etc/motd to change this login announcement.
root@test:~ # ping 192.168.178.1
PING 192.168.178.1 (192.168.178.1): 56 data bytes
ping: sendto: Network is unreachable
ping: sendto: Network is unreachable
ping: sendto: Network is unreachable

ping: sendto: Network is unreachable
^C
--- 192.168.178.1 ping statistics ---
6 packets transmitted, 0 packets received, 100.0% packet loss
root@test:~ # 

and I double checked => the option "enable_raw_sockets" is enabled => where is the issue?

 

[Sepphod]

finally I could make it => I needed to disable IPv6 and no VNET => I don't get it
