Hi All

My problem is to get Shiva VPN Client getting through my ADSL router (Nokia M1122) and establishing connection. I can establish VPN link through direct 56K dial-up connection, but when trying to do the same over the network, through my proxy server and to ADSL router,although typing correctly IP address of the remote server and getting messsage that "secure connection is established",I also keep getting message "Unable to obtain client IP", which at my opinion occurs after remote server requests client IP and WINS/DNS info from my computer. Does anyone have idea how should I configure my Proxy Server and/or ADSL router to make Shiva VPN Client work. (I getting my IP address from DHCP server on my LAN.)

Thanks in advance

Hi Drakich,
The problem is because you are trying to access a Shiva proteched site using spoofed IP addresses.
See your clients use a Proxy Server to get on to the internet. This way only one IP Address is used by all & shows only the Proxy IPto the outside world.
When these clients reach the Shiva Protected site, the shiva VPN takes the IP Address from the first client & logs it. however it checks it thru VPN & finds that its actually something else - that means someone is trying tohack in using a spoofed IP, Thus itrejects it.

The Solution:-
1. Connect systems to the Switch where your Proxy is connected (along with the Router).
2. From your Router create a Tunnel having gateway IP as 192.168.15.1 & make a source-detination Tunnel to the Shiva Router (give it IP as 192.168.15.2).
3. Now give IPs to clients as 192.168.15.20 to 254 using gateway as 192.168.15.1.
