enterprise vault proxy server for OWA

Hi all,

at the moment we're running one single EV server within our company LAN. In order to make archived items accessible from the internet via OWA we would like to install a second EV server which would act as a proxy.

Can anyone tell me if this is possible?

we habe:

exchange 2010

EV 10

P.S.:I'm aware that there is also the possibility of publishing an URL for the EV server via a firewall but due to security reasons the network team doesn't allow this. They force us to search for another solution, therefore my question above.

Thanks, Roberto
