We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
I have recently bought an Epson ET-2650 printer. Now my pc can see it on the newtork and it can print fine. However, when I try and register it via the Epson connect setup utility, so I can register it and print remotely, it won't work. I have narrowed this down to the fact it requires port 5222 to be open which isn't. I have forwarded that port to my printer but it still remains closed, so I can only assume that BT are blocking it for some reason. Is anybody either able to confirm this, or point me in the right direction to get this resolved ?
Solved! Go to Solution.
Assuming a Windows pc, have you checked that Windows firewall allows access via that port?
I am using canyouseeme.org
I have successfully tested other ports as follows:-
Port 5001 shows closed on canyouseeme
Port forward set up for this port to point to my NAS drive
Port 5001 now shows open
I have also done this with a few other ports successfully, but no joy with 5222, which is why I am guessing this is possibly a BT issue.
BT do not normally block any ports, are you sure your printer is allowing incoming connections on that port, have you tested it locally on your LAN to see if the port is open?
I assume its TCP?
There is a Microsoft utility do do that.
It may be that when you are checking the port the printer has gone into power saving mode, standby or whatever term Epson uses.
BT are not blocking the port (5222). The first image shows the port stealthed when the application used for testing is not running, like a device in standby.
Second image shows port 5222 open when the application is active and listening.
Thanks Liam - I have confirmed the printer isn't in power save mode / standby.
Thanks Keith - The results were as follows which shows something is filtering this port. I have turned off my router firewall and the windows defender one, to no avail. I also have the port forwarded still. I also have a MAC and that is the same, with either firewall off, or on with port access allowed. The .100 address is obviously the ip address of the printer.
Starting portqry.exe -n 192.168.1.100 -e 5222 -p TCP ...
Querying target system called:
Attempting to resolve IP address to a name...
IP address resolved to Epson
TCP port 5222 (unknown service): FILTERED
portqry.exe -n 192.168.1.100 -e 5222 -p TCP exits with return code 0x00000002.
The router firewall should have no function using portqry on your local network. I notice you have the printer IP address assigned by DHCP, which is not a good idea on a home hub.
Go into the front panel and give the printer a static IP, outside of the DHCP range. I have my Canon printer on 192.168.1.60.
That will overcome one of the issues with the DHCP server on the home hub.
Are you sure the printer used TCP and not UDP, as I have never bothered with remote printing, as it seems pointless as you cannot see what is being printed out.
I assume you can print out locally from your PC?
There are some strange issue with home hubs when it comes to sharing connections, which is one of the reasons I do not use one.
