VPN 3002 and ISDN

Hi Guys,

I'm experiencing some problems with a VPN3002 Hardware client connecting to the Internet using a 801 ISDN router. The client brings up the line every 9 seconds even if ISAKMP keepalives are disabled on the central site (VPN3005 Concentrator).

The logs on the 3002 says

1027 05/20/2002 19:01:07.930 SEV=9 IKEDBG/0 RPT=796 VPN-3005-Public-IP

Group [VPN-3005-Public-IP]

SENDING Message (msgid=a432563f) with payloads :

HDR + HASH (8) + NOTIFY (11) + NONE (0) ... total length : 76

And the route brings up the line for a UDP 500 connection (ISAKMP)

Can someone help me?

Thanks in advance
