I'm assuming that the node 192.168.37.1 has a default route of 192.168.37.254 (the BIG-IP)

 

 

If so, and you're using ICMP, it looks like SNAT hasn't been configured to allow ICMP (by default, SNAT only forwards UDP and TCP packets)

 

 

Try enabling SNAT Packet Forwarding for all packet types:

 

In the GUI, navigate to: System>>Configuration:Local Traffic:General

 

Change "SNAT Packet Forwarding" from "TCP and UDP Only" to "All Traffic"

 

 

Your ping to the router should now work (I'm presuming that the router doesn't have a route back to your BIG-IP for the subnet 192.168.37.0/24)
