Can I ping my business's server from my home?

view story

http://serverfault.com – Admittedly a very noob question, but I haven't found a straight answer. I have a server running Windows Server Standard 2012 at my office. It is part of a small 2 computer LAN. I've setup a VPN on this server in hopes of accessing it from home. Connecting to the VPN works within the two-computer LAN. However, I'm unable to connect from any computer on a separate internet connection. Digging into it, I can't even ping the server's public IP from my home. I've ran a tracert on the public IP and it tracks for 7 instances or so, then fails. Pinging from within the LAN works fine. All firewalls (HowTos)
