The tunnel is for manage some network devices what are using private IP from network 172.26.3.0/24. Now if I ping from publicIP (it could be server with nagios). Echo request packet is routed through tunnel and reaches 172.26.3.1(device) but echo reply is routed via default route on netB gateway and NATed out to internet. Question: Could I somehow discover that echo request traveled by tunnel so reply should take same way?
