Hello everybody! I'm trying to setup Debian 10 as a router. I think, i can't make the right nft configuration. So, what i'm doing wrong?
Code:
#!/usr/bin/nft -f
flush ruleset
define wan = { ens5 }
define lan = { enx8cae4ce9bb0c }
table inet filter {
chain input {
type filter hook input priority 0; policy accept;
ct state {established, related} accept
ct state invalid drop
iifname lo accept
iifname $lan accept
ip protocol icmp accept
tcp dport 22 accept
}
chain forward {
type filter hook forward priority 0; policy accept;
iifname $wan oifname $lan ct state related, established accept
iifname $lan oifname $wan accept
}
chain output {
type filter hook output priority 0; policy accept;
}
}
table ip nat {
chain prerouting {
type nat hook prerouting priority 0;
}
chain postrouting {
type nat hook postrouting priority 100;
#ip saddr 192.168.1.1/24 oifname $wan snat 192.168.0.11
oifname $wan masquerade
}
}
I have ssh connection from both devices to the "router", just i'm not able to build a connection (NAT) between both of if. If someone wants to share with me working /etc/nftables.conf without any restrictions (two interfaces), or just to explain to me what i'm doing wrong, will be nice
