Configure WRT54GS Running DD-WRT To Connect to Office VPN Connection

I have configured a Linksys WRT600N to connect using PPTP to my company’s VPN server in the past as noted in this previous article. I have since swapped out the Linksys WRT600N with a Linksys WRT54GS because I wanted to replace the antennas with larger antennas to work on getting better wireless coverage in my workshop in the basement and with the primary wireless router being located on the second floor of my house I needed to do numerous things to squeeze as much signal as possible. I also noticed numerous other issues with the WRT600N including the router locking up on a regular basis as well as dropping connections.

Linksys WRT600N With dd-wrt Firmware VPN PPTP Client Connection to Linksys RV016 PPTP VPN Server

A company I work for has a VPN connection at the office and from time to time I need to pull firmware, software, or various documents from them. Other times there are a couple Linux servers on the local network that I need to work on so I can either SSH from the outside or create a VPN connection and hit the devices through the local network. The amount of data I am pulling from the local network has become more frequent so I needed to find a way to not have to create a VPN connection from my laptop so often and was thinking that it would probably just be easier to connect my Linksys WRT600N router running dd-wrt firmware to the office VPN server. This way I would always have a connection to the office without having to interrupt work and create a PPTP VPN connection.
