VPN Question

I have to connect to a VPN every night from my pc at work to transmit data to a client. When I connect to the VPN, I lose all my other connections to the LAN and any other outside connections I have. I do alot of work from home, so I would like to be able to connect remotely to my work PC (VNC), but I cant as long as Im connected to the VPN. I thought of installing another nic card, but Im not sure it would work. So.. my question is, how can I connect to a VPN - and not have it interfere with other connections.

Thanks in advance.

Sounds like your VPN configuration routes all traffic thru the VPN tunnel.

You didn't state what VPN software you're using, so getting specific is difficult, but you need to alter the VPN software configuration so that only packets destined for your corporate hosts are routed thru the tunnel. Traffic not headed for those hosts goes to your router normally.

It sounds like your administrator needs to enable split-tunneling which allows you to surf the Internet AND also connect to your VPN at the same time.  I recently ran into this myself and had to change just that to make it work.

PsiCorp - Im using Nortel Networks Conectivity VPN client. Any idea how to do what you describe with this set-up?

TJanousek - I have administrator level access to the domain & local PC. Can you descirbe how to enable split tunneling?

Does anyone think installing another nic card and giving it another IP would work?

Thanks.

What type of VPN are you connecting to?  I am using a pix 520 myself, are you connecting to a Cisco device?

Im not sure what type of VPN I am connecting to - as it is just a customer. Any changes that I make would have to be on the client side.

It sounds as thought the VPN tunnel is becoming the default gateway for all packets from your lan. I don't know your particular hardware, but first of all try using tracert in a command window to find out where the packets are being sent, ie tracert to www.microsoft.com when the VPN is down, and then  again when it's up. You may need to use the IP address because it may also be that the VPN setup is taking over your DNS lookups as well.

You should be able to configure the VPN via a netmask to only carry packets intended for the client connection, and hence allow all other packets to go as they would normally. USe the "route print" command to view the local machines routing table before and after connecting the VPN to give you some more clues (I assume you are using windows, if not there are equivalent commands for linux etc).

You can also set up permanent routing tables in your machine that will direct packets according to their destination to get round this.

Let me have more info about the setup - and perhaps listings of the various tests I've outlined and I'll see if I can give you any more clues.
