[DSL] Now Blocking Inbound Port Traffic?

Up until yesterday at 2am inbound port forwards were working fine to my DSL modem. At 2am they stopped and my modem was rebooted.

Now I can't access them and when I do a port scan I see this:
Not shown: 1675 filtered ports
PORT STATE SERVICE
20/tcp closed ftp-data
21/tcp closed ftp
25/tcp open smtp
500/tcp closed isakmp
1723/tcp closed pptp

Frontier swears up and down they changed nothing. This smells like a "Great Firewall of Frontier".

Anyone else?

Re: [DSL] Now Blocking Inbound Port Traffic?

So more on this.... the DSL modem is showing the incoming traffic as "Blocked"... what on earth?
The firewall is set to None/Off and the Static NAT is configured. This modem literally has not been touched in months.

Now almost 2am... after hours on the phone with tech support, I removed the Static NAT and setup a slew of port forwards... they seem to work.

Why after three years the Static NAT just decided to stop, I have no idea.
