1.) Workstation from my end sends UDP request to a server through IPSEC tunnel
running between 2 Cisco devices
2.) Packet hits the server and server responds back with a reply.
3.) This reply packet traverses through the VPN device at Location B Client side
4.) But no traffic seen after decryption on the VPN device at
Location A (local end, my side). We are running a sniffer on the inside interface of
the VPN device.
5.) We suspected some issue on the local VPN router and did an IPSEC
debug. We get the attached output when ever a request is initiated
by the client. This output may be specifying the packets from the server.
It seems like the VPN device at Location A (local end, my end) is unable to decrypt
