Actually both rules should contain "--icmp-type echo-request", as you 
want to redirect only the ICMP echo request type (aka ping).

However, I'm wondering... It seems the gateway has private addresses on 
both sides, so why do you bother with NAT ? Why not just ping the actual 
device address 10.1.1.2 instead ?
