default gateway missing after setting static ip

After setting a static ip to allow me to forward ports,when computer is turned on I have no internet, msconfig shows a blank for default gateway. The default gateway address is also missing from the "manage network connections" window.
When I manually enter it into the window every thing works as it should until I turn the computer off. There is another machine on the same wired network, dynamic ip that works fine.

Any help will be appreciated, Old Dog

 

Did you make sure the static IP address that you assigned is outside the DHCP range of the router?

You may find this link will help.

Thanks for the reply, I configured the router to allow 10 dynamic addresses and set the static outside that range. I used the Portforward guide to set the address. I just had a thought while writing this answer, I might have to allow the static address somewhere in the router settings. I'll check it out. Thanks again for the reply.

 

No that didn't work. Fair dinkum it's doin' my head in! I will put it on the back burner and try again some other time.
Thanks for the assist.

 

Did you enter the static IP in IPv4?

Yes tgell'
I followed the portforward guide exactly, plus a couple of others. As i mentioned it works fine if I manually enter the ip in network connections. It just disappears on boot up. I have now a serious connectivity problems that I have to sort out with my ISP before I can have another go at the port forward

 

It looks like you are not alone.

I have been reading through a few threads and it seems some of the problems have been resolved by either updating the NIC drivers or resetting TCP/IP.

 

Back on line, ISP'S are a blight on humanity.
I had to re-set the modem to factory defaults and re-enter all the details when sorting out problems with my ISP, I then went through the port forwarding process again and it was successful. I have no idea why it didn't work before but all is good now. I would like to find out why and will follow those threads suggested. Thanks again for your help tgell.

 

Glad you got everything sorted. Thank you for the feedback.
