I can not reach a PPPoE client from the outside

Unanswered Question
May 16th, 2008

I have a PPPoE server on the router. The PPPoE client (adsl-modem in my case) recive an IP-address (real IP assigned by ISP) from the Radius server. The Client works well, the laptop attached to the adsl-modem have an access to the Internet. But I can't ping the client by its IP-address. There is no any firewall.
