How to connect to CUCM through a proxy (Port Forward)

[assadniang]

Hello,

I am trying to connect to CUCM UI through a proxy (or Jumpserver) with my laptop 

CUCM (Private network) ----JumpServer----- Laptop

My CUCM is located on a private network @ 172.30.6.150

I have configured SecureCRT to port forward to the IP address of the CUCM on port 443 so I can browse through it

So, I point my browser to https://127.0.0.1:3019

I can see the login page https://127.0.0.1:3019/ccmadmin/showHome.do , but when I enter my credential and try to login, it redirects me to https://172.30.6.150/ccmadmin/security.jsp , and I get "Page Cannot Be Found"

I did this with other WEB UI like ESXI host, and it works, but cannot get it to work with CUCM

Try adding port 8443 to the redirect.

Hello,
I did, and still does not work

[Roger Kallberg]

Then you're likely not be able to get this working through a port forward like you're trying to do. Please have in mind that CM or any other Cisco CVOS system isn't built to work in this way.

Ok, thank you

I am able to get it to work with other Cisco product such as Cisco CSSM on-prem satellite server, DNA-Center and ISE-Server, just not CUCM.
