ISP change and I can't connect to internet

Hello good day

Today I changed my internet provider. Before I have the omv working perfectly with a lot of services ... what happens to me is that when changing ISP now is impossible to connect the server to the Internet. ping not work, atp-get update not work too...

I've put a fixed ip settings 192.168.1.7, 255.255.255.0, gateway 192.168.1.1 and dns I've tried google, and with my ISP.

Is impossible for me, I tried to run omv-firstaid, relocating a fixed IP, DHCP .. but nothing works. Lan works, but No internet

The strangest thing is that if I make a new install everything works properly with the same configuration as the server already created.

Would have to reconfigure the server all over again and I think quite unnecessary work

It's all very strange, and I do not know what else to do, any idea.

thanks a lot

ok , I found the solution.
The problem was that at the beginning had a problem:

I solved rebuilding the symlink
thanks for the help
