Blocked port 587
I just recently took delivery of a Xerox workcenter 7225 multifunction scanner printer. It replaced a Xerox 7120 that I had previously. The printer utilizes port 587 to access a GMX.com SMTP server to forward the faxes it receives to my email address. It appears that port 587 is blocked. I have forwarded 587 on the Netgear router and I have also tried disabling the Windows firewall. However, whenever I access the website canyouseeme.org I am unable to "see" port 587. I have contacted Comcast technical support and was told that the port was not being blocked HOWEVER the tech later sent me a screenshot of the "proof" that Comcast was not blocking this port IT WAS A SCREENSHOT OF MY NETGEAR ROUTER'S PORT FORWARDING RULES! Can someone please tell me how I can get port 587 unblocked on my system? Thanks
Re: Blocked port 587
Does anyone even read these posts? I would think that Business clients would get at least some modicum of response. How on earth or we supposed to run a business, when nobody responds to problems. I've been on hold for over 30 minutes with the Security phone number 888-565-4329 and still have not talked to anybody! I know it's Saturday but I thought it was 24/7 support and this an important issue.
Re: Blocked port 587
Port 587 is the port your workcenter accesses. You are thinking completely backwards here. In fact I think you lack an understanding of these issues and you really need to call an IT consultant to straighten things out for you.
Just a few points:
There is an "inbound" and an "outbound" direction for traffic. Your workcenter wants to contact a mailserver on port 587. It is not a mailserver itself (at least I have never heard of a photocoper also being a mailserver) It does not want things on the Internet to try to contact it on port 587.
Port forwarding is for if you want to setup something on your inside network that accepts incoming connections. It is not for if you want to have something on your inside network reach out to servers on the Internet. You do not port forward 587 on your cable modem unless you are running a mailserver.
The only outbound port Comcast blocks is port 25 and that is only blocked in the cable modem. And it is very easy to unblock. And it has nothing at all to do with your problem.
Lastly, most copier techs I have talked to are utter morons when it comes to networking. They do not understand it but they think they do and they spew misinformation to every customer they talk to.
If your network and business makes enough money to support that copier you owe it to yourself to find a real IT consultant. I know it looks like it's easy and you just plug in some things that look like oversized phone cables and everything works. But in reality it is a vast conspircy to make networking look really simple to do so that business owners grind their teeth every time they have to spend money on a consultant who comes in, taps a keyboard for minutes, then leaves and charges them $100 bucks.... just kidding!!
