I have a T1 line that goes straight into a Cisco router, today it just started blocking all ports out of the blue, I've been trying to figure it out but i can't, i've even removed every resemblance of security on the router and made sure that there is nothing other than a permit any ACL assigned to the NAT. its completely wide open, yet i can't get into anything. I called the ISP and they said they never block ports, that its just an open pipe into our building. So its gotta be an issue on the cisco. I've attached a copy of the running config. Let me know if there is any more info I can give, i'm afraid i'm running on empty as its 1:00 am and i've been up since 6:00 am yesterday lol, so i may have left something out.
