I'm currently setting up a VPN connection possibility for some of our 'nomad' workers'. Having no prior experience with VPN, I'm somewhat stuck as the documentation / help files do not really cover the gap between hardware and software solutions.
My network involves 3 servers, and say 25 PC's/Notebooks. The solution I'm implementing involves a Zywall 35 firewall (as my netweorks default gateway and DCHP server), and Zyxel Security VPN client software for the notebooks. The Notebooks and PC's use Windows XP pro, server OS is Winsows Server 2000, SP4)
I have no problems in getting the tunnel up and running, and I can ping the computers (by IP address) on my office network from the VPN clients over the tunnel. The VPN client however does not seem to authenticated on the domain network, as I can not use any of the mapped drives or access the defined shares.
1.) Do I need to establish a tunnel first, and then logon to the network (and if so how can this be done?)
2.) Despite my implementing a hardware solution, do I need to activate remote access service on my main server?...
3.) and do I need to set any special permissions or create/modify a policy?
4.) The domain DNS server address does not seem to be forwarded properly, as I need to modify the host file by hand and add the entries in order to access them by name.
Any answers to above will probably raise more questions, but thanks anyway for helping me out on this one.
