Dear All Expert,

Now i implement VPN site to site from HQ to ATM offsite, so the VPN connection is ok( i mean it is working so i can remote to ATM machine and ATM can process money too) but my problem is sometime ATM machine it out off service during it out off service i can remote to ATM machine and connection is OK from HQ to ATM.

i don't know how to troubleshoot?

This problem the ATM guy the said the has the problem with Connection or ASA equipment..but i don't believe it bec i don't block UDP,TCP , i allow one subnet to one subnet......

how can i do on this? how can i don't the connection and equipment don't have problem?

Best Regards,

Rechard
