How to deny external network access to Redis in the local network?

January 05, 2023 · 1345 · 1 min

When I recently set up Redis on the local network, I found that if there is no restriction, everyone can access it, which is very unsafe, so it is necessary to set up to allow only local access to Redis and deny all external network access.

To achieve this effect, use iptables.

# Only allow local access to Redis

iptables -A INPUT -s 127.0.0.1 -p tcp --dport 6379 -j ACCEPT

# All other ip accesses are denied

iptables -A INPUT -p TCP --dport 6379 -j REJECT

After the above commands are configured, Redis cannot be accessed from the external network. The stored data also has a security guarantee.
