What would be the security issue? NAT does not add any security - the firewall does. Just because you have publicly routable addresses doesn't mean they're publicly accessible.
- StavrosK 13y agoNAT is a good "disallow everything by default" firewall. If my router's firewall had a "disallow all incoming connections by default, it would be great, although I guess I should manage it with iptables, which is machine-specific.
- zaphoyd 13y agoMost ipv6 enabled home routers have firewalls with a "block all incoming connections except for listed exceptions" feature. This effectively gives you the same security as NAT but without the port mangling (can run multiple machines on the same port).
