ISP's That Firewall Customers


Recommended Posts

They already disabled ping, traceroute, and port 135.

Now there going to block port 25 will it ever stop? :angry:

PORT 25 BLOCK

In order to increase the security of our network, we have deemed it necessary to close the communications port (Port 25) used by e-mail worms to spread from user to user. This change will be implemented in phases over the next few weeks and will eventually be applied to all Residential and Dynamic IP Business customers. This is a standard practice among Internet Service Providers.

This will not affect normal use of your service. If you send e-mail through another ISP's mail servers while connected to the Knology network, you will receive a send error in your e-mail client. This does not apply to web-based e-mail such as Yahoo or Hotmail, nor will it affect customers that connect to AOL over Knology. You will still be able to receive e-mail from accounts other than Knology's, you just need to be sure you send mail out over your Knology account.

Thank you,

BiGdUsTy: This is not to protect the people who have firewalls; it is to protect the people without firewalls. "The Actions of Few Effect the Actions of Many". I am not sure how Knology is handling it, but Cox HSI here in phoenix will let you send out emails through their SMTP for other domains. If this is the case, I don?t think it would be a big deal. If it isn?t the case, I would have a problem with it. They are trying to minimize the effects of viruses that send through SMTP servers and also spammers who use their service.

bigdustry: I am not sure how your ISP has set the block up. With Cox, I can still send mail out from another email address (IE: frank@wosnetworks.com) BUT i have to send it through THEIR mail server (IE: smtp.west.cox.net) instead of mine (smtp.wosnetworks.com). It still goes through, it still is from my email., but it goes through their server. They authenticate it through my IP address and MAC addressing (I believe) so it is not a open Relay.

sinatosk: how is this stupid? It cuts down on spam, and also stops the sending of visuses. It also speeds the network up when viruses are being sent around BECAUSE it is not being sent from the Cox Network.

I hate when ISPs go blocking ports, I think it would be better if they just sent emails to their users instructing them how they can protect themselves

Didn't Microsoft send emails and have stories sent out urging people to update their system before the blaster virus started getting sent out? It was even on my local news. It is not a 100% FIX to contact users. It is a 100% fix to block port 135 (in blasters case).

Either you've misunderstood their actions, or they've taken the incorrect actions.

Its only necessary for them to block incoming port 25 with a destination amung their customer base. IE: They block any access on their own IP range to port 25 (ie locally), but allow access to port 25 on their mail server, and any external mail server.

THIS WILL NOT PREVENT YOU RUNNING A LOCAL SMTP SERVER ... if the ISP have set it up correctly.

Its a VERY sensible move to prevent spam.

However, they claim to have set it up to block worms, this is the wrong thing to do, which implies they've set it up badly. Sh1t ISP, i suggest moving. The firewall admins dont know what they are doing if its the latter case.
