I have set up my DM 7020 for c/s and did everything to manual but....

Cccam is ok, communication setup also, dns server also, Ip also, but it simply won't connect to other users outside.

A really strange thing is that when I try to telnet its ports, the port I have forwarded in the router but also normal ports like 21, 23 or 80, it won't telnet to them !!! I have used the program putty to connect via telnet but it simply won't connect through any port.

Any advice would be much appreciated as I do not know what to do anymore :(
