Iptables in DietPi

Troubleshooting
#1

I’m wondering if there is something like iptables installed with DietPi as default or a firewall?

I would like to make sure that DietPi accepts connections from port 41.
I tried running iptables -I INPUT 1 -p 41 -s SERVER_IPV4_ENDPOINT -j ACCEPT
Saw that iptables is not installed so does this mean that there is no problem with connections through port 41 or does anything else inside DietPi maybe be blocking connections to/from port 41?

I’m trying to setup ipv6 routing with a Hurricane Electric IPV6 tunnel and radvd (if this makes thing clearer).
Trying to troubleshoot why i can’t connect to the server over ipv6.

Thanks in advance!

Iptables is not installed by default, however, some of the applications in dietpi-software will automatically install it, if needed.

does anything else inside DietPi maybe be blocking connections to/from port 41?

Not that i’am aware of.
