  1. F5 Edge Client VPN

Issues that I have seen is when the F5 APM device is upgraded to not be any longer compliant with the old VPN client on the user systems. Also I have seen issues with slowness for VOIP or file download and upload and the solution was to use DTLS not SSL for the VPN. For the F5 VPN solutions in many cases from the agent the diagnostics logs need to be gathered and reviewed as from the F5APM the logs could be not enough. Because the MTU of the installed Edge client agent can't be configured better to play with the Network Access Virtual server and it's TCP profiles if needed or try DTLS when there are issues.
