The problem - R2 and the devices on the R2 network cannot ping R1 or R3 - R1 and R3 can ping each other just fine, R1 / R3 can successfully send a packet to R2 but cannot receive them as the packet stops at the R2 router upon sending the ping request back.
((Btw R3 is using S 2/0 not S 3/0 - That was a typo)) Configs
