Thank you Scott.
If i do "dlsw udp-disable" then UDP (2067) packets are out of question right...
So may be i should do this if i have to block these packets over
isdn.. I can configure to not to initiate these from the beginning
itself ... And the deal with TCP 2065 on the dialer-list to deny.
Cert.
