PING: this works fine: ping 10.20.1.7 PING 10.20.1.7 (10.20.1.7): 56 data bytes 64 bytes from 10.20.1.7: icmp_seq=0 ttl=125 time=1.633 ms --- 10.20.1.7 ping statistics --- 21 packets transmitted, 21 packets received, 0% packet loss So the server is there, but the access is not. That is my conclusion. Is that how you see it? regards, Trevor
