Hello,

I thought I could host a snowflake standalone proxy in my home fiber. Following the instructions[0] it says that is "especially recommended":

A full-cone NAT (you can use this NAT behaviour tool to test what type of NAT you have. The properties you are looking for are address-independent mapping and either address-independent or address-dependent filtering)

Using the "NAT behaviour tool" I get: * NAT mapping behavior: endpoint independent (good) * NAT filtering behavior: address and port dependent (bad)

My home router is an openwrt on which I have total control, it gets the public IP from my ISP and provides NAT to my home network. I tried playing a bit with the NAT Rules and the firewall settings, but all that is magic for me. Any tips how to fix the NAT filtering in openwrt or what do I need to look into iptables for it?

Thanks.
