    I'm trying to set up a VPN connection from the corporate network to my home
    network. I need to use a VPN connection because company policy does not
    allow the use of Remote Desktop. My home network consists of 3 computers
    (all XP Pro) sitting behing a Zyxel Prestige 660HW router/firewall with VPN
    capabilities, which in turn sits behind a DSL modem.

    I've been reading all over the place and I'm still not clear on the

    The home network is set up as a workgroup. It's set up behind NAT in the block. I have a dynamic IP, but I'm using a dynamic DNS
    service (which I'll call

    The work computer is part of an AD domain, and uses NAT in the
    range. I don't know the firewall setup, nor do I have any sort of access to

    In the VPN/IPSec settings of the router, I've set up the following:

    Menu 27.1.1 - IPSec Setup

    Index #= 1 Name= //not real address
    Active= No Keep Alive= No //not yet activated
    Local ID type= DNS Content= 12345
    My IP Addr=
    Peer ID type= DNS Content= 12345
    Secure Gateway Address=
    Protocol= 0 DNS Server=
    Local: Addr Type= SUBNET
    IP Addr Start= End/Subnet Mask=
    Port Start= 0 End= N/A
    Remote: Addr Type= SUBNET
    IP Addr Start= End/Subnet Mask=
    Port Start= 0 End= N/A
    Enable Replay Detection= No
    Key Management= IKE
    Edit Key Management Setup= No

    In the Key Management Setup:

    Menu - IKE Setup

    Phase 1
    Negotiation Mode= Main
    PSK= 12345678
    Encryption Algorithm= DES
    Authentication Algorithm= MD5
    SA Life Time (Seconds)= 28800
    Key Group= DH1

    Phase 2
    Active Protocol= ESP
    Encryption Algorithm= DES
    Authentication Algorithm= SHA1
    SA Life Time (Seconds)= 28800
    Encapsulation= Tunnel
    Perfect Forward Secrecy (PFS)= None

    The router manual isn't much help. I'm planning to create the connection
    using the XP client from work. I haven't tried it from work yet (will do it
    tomorrow), but does anyone see any glaring errors in the above configuration
    that might not cause it to work, so that I can change it today while I'm
    still home?

    I also plan to be traveling quite a bit in the next few months. Would this
    work no matter where I am? (of course, if I'm not inside the company's
    network, I have a chance of being able to use RDP).

    Not sure of the capabilities of the Zyxel router but what does VPN
    capabilities mean?

    Many routers have a VPN pass through but on your home network you will
    need some sort of VPN server.
