My Tech Notes

I recently inquired RCN (my Internet provider) about their policy on blocking port. I didn't really expect an answer, but after a period of silence they responded:

Port 80 inbound
Port 25 inbound
Port 25 outbound
Port 135
Port 137
Port 138
Port 139
Port 445

In fact, the reason I posted this inquiry to begin with was that I noticed that port 443 (https) is now being blocked, or so it seems. However, from their reply it seems like no. Well, maybe I am wrong somewhere. In any case, it is good to al least have an official list from RCN.
