Yes, you Citrix Meta XP has a web enabld option. You can post this through any SSL based VPN. This actually works alot better then using the fat client especcialy if you have a remote sales force that need to connect to it.
In the WVPN you would just point it to http://server_name/ and let the WVPN hardware do all the bridging of SSL for you so your server doesnt take the load.
