No end-to-end connectivity through the IPSEC tunnel

[sfanayei]

I have a IPSEC tunnel between site A “4331 router” and site B “C800 router”. And a Win10 machine are connected to LAN site on both behind both router. Ping from site A to machine behind router B brings the tunnel up and debug for isakmp and ipsec shows that both phase 1 and 2 completed, and ipsec #pkts encaps: and #pkts decaps: counter increases in site A router but only  #pkts decaps: increases on site B router. No end to end connectivity. What is wrong? Please help. and tanks in advance.
