What if someone sends you a packet with 127.0.0.1 dst address?
I'd better use something like this:

sudo iptables -A INPUT -i lo -j ACCEPT
sudo iptables -A OUTPUT -o lo -j ACCEPT

Done. Agree that an interface-based approach is more secure than an IP-based approach here.

We have assigned 2 ipv4 address to lo:

  1. 127.0.0.1
  2. loopback address

I thought this method will allow more than we expected.

Good point. Changed: Now accepting all incoming traffic on lo iff it has the localhost source IP.
