Without reading over the lab does R1 know to go through VPNC to get to 172.16.0.0 network?
Can you ping 10.2.2.5? Tyson Scott - CCIE #13513 R&S and Security Technical Instructor - IPexpert, Inc. A Cisco Learning Partner - We Accept Learning Credits!

R4 & VPN Concentrator have reachability through R4 Serial interface but problem occurs when R4 lookback100 (172.16.0.1) tries to reach Concentrator. Therefore, encryption/decryption also doesn't happen. Attached is the output and configuration files from R4 and R2. Do I need another static on R2 to route 172.16.0.0 network?

Verified the configuration by connecting test PC as VPN client. Configured R4 as VPN client but ping test failed as captured below. IKE phase-1 and Phase-2 are established (sh output is attached). I'm not sure what is missing? Appreciate any suggestions/pointers. Thanks, -Anshul R4#ping 10.2.2.1 source loopback 100 Type escape sequence to abort.
