Hi Expert,

SYSLOG:"start_t4 - timer T8 already running"

Please tell me about above syslog message.

This case is following network diagram.

[ISDN RT1]-BRI0---<<<IPSEC over ISDN>>--[ISDN RT2]

We could not  connect to ISDN-RT2 by IPSec over ISDN.

Maybe I think that this trouble may be caused by those syslog message.

Those syslog message was many output on syslog server.

Please help me.

Regards,

Takuro
