Local network printing with a VPN

By col ยท 5 replies
Aug 1, 2004
  1. I connect to work through a Cisco VPN. My home office has a broadband router with two computers and a network printer. I can print from either computer as long as I am not connected to the VPN. However, I would like to be able to print when I am connected to the VPN.

    I have enabled Local Lan Access on my VPN settings, but once connected the Properties window says that Local LAN access is disabled.

    Any suggestions as to how to configure my system so I can print on my network printer while remaining connected to the VPN?

    Are you using a VPN client to connect to the system? That would complicate matters, a lot.

    I'm using a VPN here, with a Cisco router. However, to "log on" to the VPN I just use the Windows logon system with my username/password. I just had to add my network printer (HP LaserJet 6 on a DLink server) to the system as a local administrator, and it was available and working under the VPN account.

    Thanks for the response. I'm still confused unfortunately. I am using a VPN to connect to my business. I can print to the queue but I have to disconnect from the VPN in order for the documents to print. Then I reconnect to the VPN. None of that is too hard, but it is inconvenient.

    So your recommendation is to create an account for my printer. Sorry to be slow here, but how do I do that? I know I can create this account through XP's user account program, but it's not clear what I need to do next.

    Thanks again for your help!

    I don't know the possibilities of Cisco VPN - there may be a way to access local machines on the same subnet as the VPN. A lot depends on the VPN policy too - what traffic is allowed where. You should consult your administrator who set up the VPN - he can tell you what is allowed and can be done.

    There may be a hard way to do this in Windows too.. Basically, the VPN client creates a new network adapter and routes all "local" traffic through that.

    You could create a specific routing table entry for your printer instructing windows to send packets to that address to your real local network instead of the virtual one. Whether you can actually do this depends on the intelligence of the Cisco software.

    Another thing to try is to use a diferent network for your home. For example if you have 192.168.x.x network at work and 192.168.x.x network at home then VPN will happily hijack all your local addresses and redirect them over the VPN connection to your workplace. If you set up your home network to be 10.x.x.x then this shouldn't happen.

    printing to a local/network printer when connected to a vpn.

    Typically, when you are connected to a vpn, the local network is inaccessable, due to most vpn clients disallowing split-tunneling. Meaning that if you are conneted to the vpn, you are connected to the other network not your local one.

    CORRECT :)

    think about it; while connected to a VPN, it any other network is accessible, then
    the remote system hosting the VPN can be attacked via your local network!
