hello,
I have allowed remote connections on my sql server 2005 and I can remotely connect. But in one wireless web, which is provided by a router with a hardware firewall, I can not establish connection to my sql server. I tried to telnet ip-port in there with failed result, but I successfuly pinged the server ip. How can I do a remote connection through a hardware firewall? I just believe it is the hardware firewall, but I think I am right since I can remotely connect from other sites (with the same notebook). I simply must make sure that everybody everywhere connects, no matter what hardware firewall is set up. How could I achieve that? Thank you guys

Log into your firewall and use Port forwarding or NAT. Map the ip address and port of your sql server to your public ip. The default SQL Port is 1433 I believe.

Look here.

thanks,
but I would rother not edit firewall settings of my server clients. For then I would have to visit every user and edit his firewall.... that is impossible. I would rather find a solution on how to have my clients connected to my server no matter what firewall they are behind. I thought of having server listening on port 80 as this port is never blocked but when I set this port on I cannot start sql server service.

hmm, the link said some stuff but I have no clue how to follow it. So I decided to turn off the firewall of my server. I will test it again from that wireless web and post the result. If I will not be able to connect, it means it is the firewall of client knocking the connection down, not my server firewall. How can I then solve this without altering client firewall?
