Last three days we are facing a constant packet loss while pinging our mail server IP , which is 3 Mbps 1:1 RF link. Due to this reason, we are unable to send mails from mail clients like Microsoft Outlook. Therefore, Monday morning I logged a call and followed all the instructions as provided by our ISP. The instructions were:-
1. To restart the canopy
2. To restart the sonicwall firewall(canopy was directly connected to it's wan port)
3. They also came to our office and checked through discooneting the wan port of the laptop and connect it directly to a laptop. Strangely there was no packet loss.
4. They recommended us to place a layer2 switch between the canopy and the firewall. Which is in place but still the problem exists.
5. Now they are telling us to replace the firewall.
Please me help to sort out the problem asap.
