HAproxy with Vmware Remote Console (VMRC) forwarding multiple ports

[blarg3891]

Vsphere 7.0 webclient over 443 works fine through haproxy. If a console session is initiated using VMRC gets an error "connection error: could not negotiate SSL." Going directly to vsphere host works fine. Based on reading other ports are required namely 902 TCP/UDP and 903 TCP. Someone revealed a working config using nginx proxy as seen below.

I added port 902 and 903 w/o SSL offloading to the front end, and removed the 443 port designation on the backend. I read that leaving the port blank will forward w/e port from the front end. However the backend is still set to "encrypt" as vpshere is only open on SSL encrypted. I think this may be part of the issue but i'm not sure. Relevant haproxy config included. I cant figure out how to specify UDP or forward the ports properly like in the nginx file. Any help appreciated.
