connecting to office from home network

[4johnny]

I am using cisco vpn client to connect to office. it makes the connection and I enter my domain username and password and it states that i am connected. However I am issued a 192.168.12.x address and our internal work address scheme is all in the 192.168.5.x range. The vpn connection also shows my dns server address is 192.168.5.1, which is ocrrect for our office network, however that machine is not reachable because i am on a different subnet.

Other users are able to connect and i am assuming they are getting issued a 192.168.12.x address as well.

I am not the one who setup the VPN configuration. Does this sound correct that the VPN server in the Cisco router is suppose to issue different subnet address (192.168.12.x) to vpn connections then regular office connections(192.168.5.x)?

If so, does the vpn server bridge the 2 subnets so that office network is available to the vpn user?

or could it be a connection issue with my home network and router?

thanks

Yes, you are suppose to use a different subnet for remote access vpns than you are for internal hosts. So the issue is that you can connect, but cant pass traffic?

Your home network isn't set up as 192.168.12.x, is it? That wouldn't be common, but an overlap between the local and remote networks will foul up a VPN.

Having a mask of 255.255.0.0 on your home or remote network would do it also. Again, not very likely.

First I'd run ipconfig /all and make sure that you can ping your gateway (probably 192.168.12.1 or 192.168.12.254). Then I'd call the one who did the VPN setup.

I installed the client on my laptop and went to a friend's house and was able to get on through his ISP and network setup. So...I am able to connect on my home network without a problem but then I can't see any computers on the office network which leads me to believe that I need to open some ports for VPN traffic. Can you tell me what ports I need to open up for my home network for VPN to work?


worked on my friend's cablevision network but not on my ATT u-verse network.

btw, Thanks for your replies

The way I have mine set up, I have a Cisco 2620XM at home that is my vpn server, and when I vpn into it from work, I get an IP address from the home dhcp pool, but I use a route map to nat so that I can exclude the vpn addresses from being natted.
