To increase the security of my NAT configuration, I opted to implement port triggering instead of the traditional port forwarding on my router. I chose this approach in order to configure it from my nix configuration.
Specifically, I have enabled port 443 triggering on my router and included the following configuration:
nftables = {
enable = true;
ruleset = ''
table ip nat {
chain PREROUTING {
type nat hook prerouting priority dstnat; policy accept;
iifname "wlp2s0" tcp dport 443 dnat to 10.100.0.3:443
}
}
'';
};
nat = {
enable = true;
internalInterfaces = ["lo"];
externalInterface = "wlp2s0";
forwardPorts = [
{
sourcePort = 443;
proto = "tcp";
destination = "10.100.0.3:443";
}
];
};
Now, after rebuilding, it still does not work and I'm left to wonder why. Are both the NAT and nftables settings even meant to run at the same time?
