Hello,
I have an odd issue with an XGS87w recently installed. We experience a lot of packet loss when using the device's WAN connection to external addresses and the reverse. The packet loss clears up for about two minutes every 20 minutes or so. The loss is also not present when using SSL VPN to connect to device. I may be missing something obvious here but the device has very basic config with allow all out firewall setup and a few VPN users. I'm not really sure how to troubleshoot this issue. We have contacted the ISP regarding the loss and they saw some signal data out of spec but then why does the VPN clear up the packet loss? Any advice is much appreciated.
Image 1 is from device during issue - There is one incoming and one consumed entry for every outgoing, I assume this is the same packet and that device is reporting that it is responding to every echo request.
Second image is from laptop during test where we see only one response packet arrive for every request.
Ping from external address to WAN address - ~50% packet loss most of the time
Ping from device to external address - ~50% packet loss most of the time
Connect from external site to VPN and ping LAN over VPN - No packet loss
