Unable to establish GW (Appliance 600) connection with SMS. After a short period of time after the connection is established, access to the Internet begins to lag. Without SMS server connection in the equation, everything seems to work fine. The connection between SMS and GW is lost, after restoring the connection between GW and SMS, the Internet is again starting to lag. I tried on two different devices model 600. On both, this problem replicates. Everything is allowed in the rules.
Why does this happen?
