Bingo!  Right on the money again.  We've had a lot of these lately.  The 
firewall product we use has the ability to drop unroutable ip's.  In the 
beginning I thought this was just 192.168/16, 172.16/12 and 10/8 but I 
soon found out it also includes a list of ip's that is marked as 
reserved by IANA.

77.0.0.0/8 and 78.0.0.0/8 was reassigned last year, but I think the ISP 
only recently started assigning them to clients.  We actually had 
similar problems from our side when our local ISP started assigning ip's 
from 42.0.0.0/8 which was formerly reserved.

In any case, it is fixed now.

regards,
Izak
