NFTables Setup

The following should be applied to the POP.

Create Forward Table & Chain

We'll want to create the Compressor Forward table and chain by doing the following:

nft add table compressor_forward
nft -- add chain compressor_forward prerouting { type nat hook prerouting priority -100 \; }
nft add chain compressor_forward postrouting { type nat hook postrouting priority 100 \; }

Forward Game Server Traffic

Now create a rule for forwarding traffic.

nft add rule compressor_forward prerouting ip daddr $ANYCAST_IP udp dport $SERVERPORT dnat to $GAMESERVERIP

Masquerade Random

Next, we want to masquerade as a mapped source port:

nft add rule compressor_forward postrouting masquerade random
