Why ? How can i resolve specific domains?

btw, i solved.

Just run:

echo '172.217.172.4 www.google.com' >>  /jail/etc/host

Obviously, I changed the ip and the hostname as i was needing. I will close this issue, but someone could need this information.

Notice the FIREWALL jail parameter Use value 1 or 0

FIREWALL=0|1|2|3|4

2: VPL service+DNS+Limit Internet to port 80 (super user unlimited)

3: VPL service+No external access (super user unlimited)

4: VPL service+No external access

Note: In level 4 stop vpl-jail-system service to update/upgrade the system

default level 0

FIREWALL=0
