I've been having issues with connecting to private chat on Xbox 360 and getting into lobbys on BO3 on PS4 because of moderate or strict nat. conf http_port 192. Suppose we do DNAT or SNAT , can we see the changes of source or destination in packet header? Kindly guide me for my queries. One of my favourite features is the TPROXY-target, which, as the name implies, enables you to proxy different types of connections. Check on the client machine, your transparent proxy should be up and running for http traffic. Redirect by měl přepisovat cílovou IP, traffic se zpracovával lokálně, zatímcto TPROXY IP adresu ponechává (což se zrovna pro účely hodí).
