VPN and IP addresses

Hi guys,

I am working for one company at a site in the UK, and have been given
VPN access to another company in the US.
My company's network uses IP addresses of the form 10.0.0.xx and the
remote company use IP addresses in the form 10.0.1.xx
I am having problems connecting to their VPN, however the connection
details work fine from home (where IP addresses are of the form
192.168.1.xx).
I think that there may be a problem with our router at work, which will
be replaced soon, and so I just wanted to ask whether there are issues
with VPNs and IP addresses if they are setup similarly on both sides?

Thanks for your help!

VPN is such a generic term, but if you are talking IPsec VPN, there
are usually problems when you have overlapping IP ranges.

It depends on your netmask for your 10.0.0.x and 10.0.1.x networks if
they are overlapping or not, so check on your netmasks for what you
are really using. If they are just /24 netmasks, the networks aren't
overlapping, and you should be fine with reguard to IP ranges.

That will likely be your problem. As for you PC which is the vpn client.
Depending on how your VPN is setup, it will use its routing table from
its LAN and VPN simultaneously. There are other implementations that
allow precendence over the other.

Check out....
http://www.netifice.com they provide SSL VPN managed service.

Also my store.

Hi,

You can use ViPNet VPN.
ViPNet can handle this issue by providing virtual IP addresses for
whole created VPN enviroment over real IP addresses. You will not need
to change anything. You could try to make it with a demo of ViPNet for
45 days.

ViPNet VPN is an IP based VPN, not SSL.
