Hi, you may have some problem with your routing table. As you said your network address should be (130.130.80.66 & 255.255.255.0 = 130.130.80.0) which is not in the same subnet of your default gateway 130.130.1.1. If you are sure your gateway 130.130.1.1 is correct, you may need to set your IP address as 130.130.1.66. Another possibility is that you have a wrong subnet mask, it should be 255.255.0.0 instead of 255.255.255.0. Check the correct configuration of your server.
If this does not work, you can su as root and use "route" to print the routing table. Paste your routing tables here (a routing table of one of your servers will be greatly helpful).
