Hi communauty,
I got this stange problem, I mande a port forwarding from my WAN to my LAN to be able to acces some service, but it work one time of two.
The DNS resolution give the write ip address.
The nmap port scanning found all port close.
Is some body have an idée what going on ?
I figured out that my server vas on bolt vlan and do not respond on the write one.
I just isolate the service ont the right vlan and everything work fine now.
