need assistance on this, users are remoting into company network using VPN client, VPN client maintains connectivity, but when users are using multiple instances of TOAD/SQLNet to access Oracle DB the idle connections timeout between 5-30 minutes. SSH also has same issue when accessing this way. problem occurred when we upgrade our firewall and switch. firewall router and switch have all been checked out, no log files of any errors from any of the hardware or on the server. oracle is running on Solaris Unix servers. users insist that this did not happen prior to upgrade hardware. we set the max timeouts as high as they would go on all hardware and still had same problem. Anyone have any ideas on this, please let me know. thank you.
