Not really, NAT will keep track of destination address as well so unless the network share outside the network is also the address of an adversary, the SMB port

Not really, NAT will keep track of destination address as well so unless the network share outside the network is also the address of an adversary, the SMB port isn't open to the internet.
- kiallmacinnes 8y agoNAT doesn't do this on its own. It would be a duplicate implementation of the stateful firewall, so NAT leaves this piece to the firewall. NAT is nothing more than a lookup table of router IP+Port and internal IP+Port pairs. (Well, PAT style NAT anyway... But that's what everyone here is talking about...)
- packet_nerd 8y agoYour thinking of the firewall that's built into most consumer routers. The exact technicalities of NAT (PAT actually) are not super well defined, and many implementations will not track the destination address.
