Can't reach GS748T Web UI outside of local network
Hello community, I have a GS748Tv5 switch on a particular network, along with a GS724TP. They have separate IP addresses (obviously) on the same network and both have the same (correct) router co...

--- It looks like it's starting to, and part of the page seems to come across, but not enough ever loads to display anything but a blank page on my screen. I can ping the switch just fine; I just can't manage it through HTTP or HTTPS.
For some context, the "outside" address I am trying to access the switch through is on the other side of a site-to-site VPN established by the router. ...
The only other thing I can think of is that it might be something related to MTU, but there doesn't seem to be any way to set MTU in the GS748.
Perfect problem analysis - must be an MTU (and PTMUD) handling problem on this switch model management IP stack.
YeZ please push this to the switch engineering for an urgent fix.

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- 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.

-KurtHi 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.
