I really need to figure out how I can connect to my chat server on my pc at home via my chat clients at work.

At work we are setup on a Proxy server. Will this effect how my work's chat clients will connect to my chat server at home?

What will it take to successfully connect my work clients to my server at home?

I know that on the lan at work I can connect all the clients to a server from work, but reaching out to my home server's IP is the toughy....

Any suggestions?
