Thank you, Kurt, for the quick response, and for the validation of my diagnostic skills. :)

I'll look forward to an update to address this. It's not critical, in the sense that I have a viable workaround, but it would sure be nice if I could access the switch when needed without jumping through any hoops. Thanks again for addressing it quickly.

Hi Sir,

Becasuse I don’t have GS748Tv5 in hands,
I test VPN connection with GS716Tv3 v6.3.1.39 (same as the latest FW of GS748Tv5)

As result, I didn't need to manually change the MTU size
and it worked through VPN and access Web UI page via http/https

I also check on GS748TV5 user manual, and found there is MTU configuration under VLAN Routing configuration,
Could it be helpful to analysis the problem ?

Jennie, Scratch the MTU config for the routing. The management port IP stack must be able to deal with the PMTUD (path MTU discovery) on its own. We have seen this issue on a few Netgear switch models recently. Its something that needs to be fixed on that very model.

  Hi Compendic,
  I try some config, scratched the MTU config on at my device, but still can access the Device http/https through VPN.
  Is it possible to povide the toplogy and captured pkts when the issue happen (can't manage switch through HTTP or HTTPS) ?
  
  Thank you.
