Access to EMS WebUI from ZTNA gateway

[AEK]

Hello EMS admins

FCT EMS 7.4.0 and FCT agent 7.4.0 on Windows 10 client.

For off-fabric clients we configured multiple ZTNA destinations, including one destination to access EMS WebUI.

All destinations are accessible and working fine except the one for EMS WebUI (browser just shows connection closed).

When inspecting ZTNA traffic on FG we see all ZTNA traffic except the traffic for EMS WebUI (there is no related log).

Any idea on what's going on?

Hello AEK,

in this case you are attempting to access a web app. Having ZTNA destinations in FCT means your are using a TCP forwarding proxy configuration. This is normally used for access to RDP, SSH or other non-web apps. For Web based apps you would use a HTTPS access proxy.

Do you currently have other web based apps added as ZTNA destinations and reachable?

Have you tried using a HTTPS access proxy configuration to access the EMS webUI?

Hello Sx11

Actually my configuration was HTTPS, not TCP Forwarding. But following your recommendation I tried TCP Forwarding and strangely it worked fine :)
