RM EasyLink reverse Proxy Solution

[KWIK]

Afternoon all, hope we are all well!!!!! Right I'm just wanting to knw if anyone has successfully manage to reverse proxy an RM EasyLink server using HTTPS. RM have told me that, I do not need a server certificate on my reverse proxy server, this being ISA 2006. I was led to belive that ISA needed a valid signed certificate bound to the vitrtual IP address of the server to allow SSL access. If it is not a ligitatley signed certificate it could then would not allow access to the server from the public Internet. At the moment I'm just wondering if this has ben done in any way by anybody out there. If you need anymore information, I will be happy to supply.

Many thanks in advance.
