Hi all, i have an issue... I backed up my vz from proxmox 3.1 and imported the backup to a new one of 5.2.1 version. Did a restore and everything seemed fine. I changed the ip of the new machine to be the same as the old one ( shut-ed down the old one ) but now the server is only accessible from within the building and not from users from outside the building as used. While doing a tracert it stops at the buildings router and does not reach the machine... Why is this happening?? Any ideas?? Thanks alot
 
Hi,

Please post output of the following commands:
  • cat /etc/hosts
  • cat /etc/hostname
  • ip a
  • cat /etc/network/interfaces
  • hostname --ip-address

Is there Cluster in your host?
Is the old PVE 3.1 still running? if YES - maybe you forget to change node name, check for that.

More thing: i recommend you to upgrade PVE from 5.2.1 to PVE 5.4 then to PVE 6.2 [1], because PVE 5 will go end of life at the end of July 2020 [2].

Oh sorry i forgot to mention that there is a cluster on the "old " configuration.. Does it matter ??? Thank you very much for your reply
