cisco 1841 vpn issue - "packet has a bad bad pad length"
Posted on 2012-09-07
Tunnel is up, and I can ping and even browse UNC paths over the tunnel.
If I try to make an ssh connection to a host on the remote side from either direction, the below message is logged and the ssh connection fails.
*Sep 8 00:56:45.202: %CRYPTO-4-RECVD_PKT_MSG_LEN_ERR: decapsulate: packet has bad bad pad length for packet: decrypt error? length destadr=10.0.104.2, prot=50, len=8
*Sep 8 00:56:45.202: %CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac verify failed for connection id=4
It's not just "bad" it's "bad bad". Or is it talking about a field called "bad pad" which has a bad length...
