Hello,
Below is a piece of IPSec VPN log. I have been trying to shed some light on why there is constant IPSec communications. 203.204.136.147 and 203.204.136.148 are ISDN router interfaces, while 203.204.136.146 is ASL (IP addresses changed in this example).
Can anyone offer input on the problem or suggest some troubleshooting procedures.
Thanks...
