I would also run a test to make sure that you have another NAT pf setup for UDP.
VBoxManage modifyvm "SERVER" --natpf1 "sw,udp,[public ip of eth0],4820,,4820" Also, is your host-only interface the first or second? How about your NAT interface? is it first or second? I only ask this because if the NAT interface was second, then you would need to use --natpf2 ------------------------------------------------------------------------------ _______________________________________________ VBox-users-community mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/vbox-users-community
