VPN Client IP problems

Postby Simple_Net_User » Fri Dec 02, 2005 12:32 am

I hope someone can help me.

Problem:

I use Netgear Prosafe VPN Client, and several D-Link VPN routers at
different locations. Setting up the tunnels so they work is no problem, and
I can connect from where ever I am located to all Routers.

But I have problems when I am located inside a local network that use the
same subnet as I have inside the remote subnet.

Example: Office with VPN Router 192.168.1.x / 255.255.255.0 - Locale subnet
of Hotel 192.168.1.x / 255.255.255.0

When both remote loacle net and locale net use the same IP range I can
connect to the VPN tunnel, but I can't reach the computers inside the remote
net.

Using e.g. D-Link DS-601 VPN Client this works just fine as I can set the
locale subnet to what ever I want in the VPN Client, but with Netgear
Prosafe VPN Client I can't figure out how to get past this problem.

Anyone have the solution to this?

Desperatly in need of good advice :-)

Renumber your office to use a less common subnet. Avoid 192.168.0.x and
192.168.1.x. Try for something less common like something in 10.x.x.x

Huuuh....

Just foud the answer my selfe, helps giving up and asking for help :-)

Solution:

- Go to "Option" Menue - Global Policy Setting
- Make sure "Allow to specify internal network address" is hocked of
- Select to use Virtual Adapter
- Now you can enter the required network address you want to use

This should work just fine.

for site2site, renumbering is mandatory. 10.x.x.x imho is also not a
good idea. i personally prefer something like 172.21.x.x.
but you're right for 192.168.1/0.x
