I think the problem come from the routes definition 

as eth0 is still up and it's the first entry to route to net 193.XX.212.0 

machine that contain this routing table will always send packet to 193.XX.212.0 from eth0 

and it's also the default route so all packet that aren't in 193.XX.212.0 network will be sent from eth0 
if you put eth0 down it will normally work because you will remove the first entry in routing table (that routing from eth0) 
but if you ping a host that isn't in the 193.XX.212.0 network you 'll have to add a default route 




hope that will help you
