I setup a full node in my VirtialBox, but it seems unstable sometime, not sure if it's related to NAT issue.
Internet Modem - AP - Laptop - VM(hosting a full node).
I checked the connections using netstat -anlp |grep "8483|8484", i saw only my VM connecting other node, no incoming connecting connected to my VM port 8483|8484.
Would like to know:
1, the impact for such setup as no other node could connect to my VM
2, what will it help if enable upnp to pass through the NAT.
