Sorry for this noob question. I have a small proxmox dc with two hosts. I've deployed a new ubuntu 20.04 server based vm on one of the hosts. From that vm I'm able to ping *any* lxc-container and/or vm with their host and fqdn name - no problem here. These lxc:s and vm:s are also available through our gateway (pfsense) using vpn. However, my new ubuntu vm is "invisible" from any other machine although it exist on the same bridge interface in proxmox. I obviously have a problem with my nameserver/dns setup. The ip-lease is correct though - the new vm is assigned a valid ip for the given network and accessing it using the ip is no problem whatsoever. I'm a dns noob so I can't figure out how to solve this 
Any indication on how to approach this is very much appreciated.
