I have a WRT54GL that I've flashed with dd-WRT v23 SP2. I've configured it with ddns, port forwarding and remote admin. Few weeks ago all was workink fine, but suddenly the router is not able to listen traffic remotely in any port (port forwarding, 80, ssl, ssh) so doesn't accept incoming connections. My ISP is not blocking any traffic, the router has enabled DDNS and it's updtating the IP well. I've flushed all the iptables, but nothing works until now. What can I solve this problem?
