SInce last week I'm the owner of a WRT54G v5. When I try to nmap, I don't get any results. NMAP says that all the scanned ports are open/filtered. When I do the same NMAP without the router, directly on the internet, I get good results (some ports open, some closed etc). I tried this in several hosts with the same results. I think its got something to do with the firewall. I tried turning this of, placing my ip in the DMZ, even tried to forward all ports to my local pc, but nothing helps. Can anybody help me with this?
