I have a 5505 that won't pass ipsec traffic from a software client, this is the error that I get from the logs.
regular translation creation failed for protocol 50 src inside:192.168.1.151 dst outside:xxx.xxx.xxx.xxx
a search of the cisco site turned up this: http://www.ciscotaccc.com/kaidara-advisor/security/showcase?case=K85809210
But I still have the issue after following those instructions.
software version is 7.2
