Let me know what more you think. Because I just shut down my Hub router's
'WAN Interface' and brought it back up and I am getting this error message
below:

*Oct 8 19:11:37.231: %CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC
packet has invalid spi for destaddr=123.0.0.1, prot=50,
spi=0xA212AFA4(2719133604), srcaddr=123.0.0.2
