I presume changing it to your 192.168.10.* domain didn't work either as you went offline for ages.

For others reading who might be able to help the OP, I tried a few things via teamviewer to get it going but nothing would work.

He has the ant connected to a router AND the router connected to a modem, the router is on the 192.168.1.* domain and the modem is on the 192.168.10.* domain.

The machine was reachable when set with a new IP, the pools were reporting alive and setting the difficulty so it suggested to me that it is connecting OK, it just won't hash so there is some other issue.
