VPN Log
The system log can often help to identify a configuration problem.
Enable IKE & IPSec logging via the web configurator at both ends, clear the log and then
build the tunnel.
View the log via the web configurator or type ‘sys log disp’ from CLI. See Appendix N on
page 347 for information on the log messages.
