Hi, I have a cisco 2811 connected by vpn to a sonic firewall. On several occasions the connection is down. In the log of the Cisco 2811 i get the following error:
%CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE packet from xxx.xxx.xxx.xxx was not encrypted and it should've been.
*Jul 19 17:38:26.293: %CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid spi for destaddr=xxx.xxx.xxx.xxx, prot=50, spi=0x1C4F247F(474948735), srcaddr=xxx.xxx.xxx.xxx
I've looked at the configurations of both the cisco as the sonic and they look fine.
Hope someone can help me with this our client is quit desperate.
