Ofc, the provider must NAT somehow my local addr behind some routable valid IP addr, in our case 82.113.99.104; without this nothing would come back, even when the 1st SYN was from my side; the question is, why they do not manage the NAT table so any SYN to 82.113.99.104 is sent to my ppp link; or if they do send it, and my ppp config is wrong?
