Hi, I have waded through many topics here and elsewhere, which I can thank for getting me as far as I currently am. There have been a number of similar situations decribed, but nothing quite the same so I would be grateful for some thoughts. I like computers and have plenty of experience tweaking hardware, but I dont deal with computers for a living and setting up a VPN is tesing my skills somewhat. Excuse me if I say something which is blatantly retarded. I am accessing my work network from home, have succeeded in making a quickvpn connection, but am not able to access remote machines (other threads I have read have been able to ping, but have problems with windows shares, this is not the problem I have). Home: Modem/Router - Netgear D834G modem/router Computers - Dell laptop (which is also used at work when I am there), XP Pro SP2 no firewall - Home-built desktop PC, XP Pro SP2, again no firewall Internet Access - 2Mb ADSL with Zen Office: Modem/Router 1 - Zyxel Prestige 650R-31 Router 2 - Linksys RV042 Computers - 'Server' which is running XP Pro with shared folders Internet Access - 512kb ADSL with Zen Having ordered the Linksys on the basis of a couple of comments I read about the relatively easy QuickVPN setup, I was rather gutted when I ran into problems getting it setup. I fiddled for ages, which we wont get into, but I will outline what I have maneged to get running. The Zyxel is working as a router, using PPPoE (lucky me the exchange seems to support it!) and its set to allow PPPoE passthough. It has the static external address for the office which was allocated by Zen (say 126.96.36.199), with an internal address slightly modified from the default (say, 192.168.2.1) and uses NAT-SUA to forward all ports to the WAN port address of the Linksys (say, 192.168.2.2). The linksys WAN1 is set as a static IP is sequential to the Zyxel internal ip, with the DNS details as provided by Zen and the gateway set as the Zyxel internal ip, it is running DHCP, is in router mode, I havent changed the NAT settings from default, and has a LAN address something like 192.168.200.1. I have turned off block wan request, though am not sure if it matters. A number of devices are connected to the linksys with static addresses (for example the two printers mentioned above, both of which have web interfaces), and some with DHCP which are a couple of laptops. I only set this new arrangment up this morning, and everything in the office seems to be working fine when my laptop is there, internet access, printing, access to the server etc (including the ability to VPN out via the double NAT using a client supplied IBM windows XP SP1 laptop to a client VPN gateway). With my own work laptop attached to the loffice lan directly I can access the linksys internal address, and also the zyxel address. When I got home, I was pleased to see that I was sucessfully making a Quick VPN connection to the office using my laptop (so far the desktop has refused, bringing up a an error message about the remote gateway, not responding but that is an side issue). My home network router is on something like 192.168.4.1, with the machines connected to it numbered sequentially. When logged in with QuickVPN I can access the Linksys internal ip (to get into the configuration page), but cannot ping or otherwise access any machines connected to the linksys (computers, printers on the lan, or the Zyxel attached to the Wan port). However, from within the Linksys configuration page I can use the diagnostic utility to ping all of the above, so they are still there. My understanding is that I must have a working VPN connection to access the Linksys configuration (at least I hope so, or my security is rather poor!) and the VPN status would suggest so both with the sofware staus on my laptop and the status page on the linksys configuration. Why then does my laptop not behave as if it is a machine on the remote network in the same was as it does when attached to the linksys directly in the office? IP details on my laptop when using quickvpn are those allocated by the local netgear router, but I believe that this is correct, otherwise it would not be able to access the internet from here to make the vpn connection. Oh, I should probably add that all addresses are set with a subnet of 255.255.255.0. If there is any other critical info just ask. I am not 100% sure of the implications of the ip ranges and subnet masks, so there is a risk I have done something I shouldnt, but to be honest I am stumped. It would at least have been clearer to me if I failed to get a connection... Thanks in advance for any help. S. Edit - The quickVPN seems stable, been up now for three hours. Having considered the issues, I would like to add that I can ping my local router just fine. I'm beginning to think it is some issue with subnet masks, in that the ranges set dont allow the local and remote networks to realise they are within the same private network. Could this be true? Though, why would I be able to ping and open the configuration interface on the linksys? Anyway, just a thought. Someone save me soon before I have to go googling for subnet mask tutorials.
