Can not connect to any ftp server from my internet connectio

Specs: Windows 7
Hi.
My problem is I can not connect to any ftp server or any database server using my home internet connection.
But i can connect to the same servers using my work internet or even using my 3G mobile connection.

I tried to contact with my service providers with no luck.

I am using a Zyxel wireless router.
Is there any settings in my router which stops me to connect those servers.

any help will be much appreciated...

If there is, it would relate to blocking the ftp port, port 23 so you can look through and see for yourself. The most likely place to look would be firewall rules.

@Curt R

the default FTP port is 21, not 23 (telnet), and the FTP data port is 20.
The data transfer itself will be accomplished through an high tcp port of the range 1024-65535.

Current routers do allow any traffic from inside the local network to the internet and uses stateful package inspection firewalls, so that even FTP, that negotiates high tcp ports for data transmission, will automatically get opened by the router, if it relates to the current ftp connection.
So FTP should generally work.

Best is, to first ask the IT guys of the company, which restrictions might block the connection from the home network.
