Browsing Internet While Connected To VPN

G

Guest

Hi,
I'm unable to browse the internet when connected to a network via VPN.

The problem is I need to have "use default gateway on remote network" option
checked on my VPN connection settings.

The VPN server is Win2k3 and it works fine when WinXP clients connects to it
via VPN.

Could anyone please help?

Many thanks in advance

4.2.2.1 is public IP. It seems to me the internet access works. The problem could be the DNS.

Hi Robert,
I figured it's something to do with the DNS at first because I couldn't get
"ping google.com" to resolve google IP address.

But when I checked the assigned DNS IPs, they were fine (the same ones on
the remote network)

However, figuring that out didn't help me much in understanding what's the
issue or how to resolve it. Hence I posted here hoping someone might be able
to help.

Anyway, many thanks for trying.

When you select "use default gateway on remote network" then all the traffic
goes over VPN interface. This includes the DNS queries also. Please make
sure that the DNS server in the corpnet is able to resolve the DNS names
that the client is trying to connect.

Hi Rama,
Thanks for you reply. The DNS at the VPN Server network works just fine.

Here are the things that I'm sure about:
1- The Win2k3 VPN Server works just fine.

2- All WinXP VPN clients that connects to the Win2k3 VPN Server, with "use
default gateway on remote network" option set, are fine and can browse the
web.

3- All Vista VPN clients that connects to the Win2k3 VPN Server, with "use
default gateway on remote network" option set, CANNOT browse the web.

4- All Vista VPN clients that connects to the Win2k3 VPN Server, with "use
default gateway on remote network" option NOT set, CAN browse the web.


I don't know what I'm doing wrong here. I'm setting the VPN connection via
the wizard while leaving everything at default. (the "use default gateway"
option already set by default when using the vista new VPN connection wizard)

Do you know, by any chance, if the procedure to setup a VPN in Vista
requires more tweaking to the wizard's default values?

Or the default VPN connection wizard values are enough to get browsing the
web through the VPN network possible?

many thanks in advance

I share you pain as I also have this issue. However, when I close my VPN
connection, I also have to disconnect and reconect my wireless boadband
service for the internet browsing to become accessable again.

Will let you know if I come up with anything, I aleady check MS's
knowledgebase with no success.

Hi Tony/Oxygen,
Can you send me the output of 'ipconfig' and 'route print -4' (routing
table)? For the routing table out put send it both before and after enabling
the "use default gateway on remote network" option.
Another thing. Would you happen to know if your network administrator
uses DHCP to assign you the routes? This info. is very critical.

thanks
Aanand

AaAnand, thanks for the follow up. However, when I unchecked "use default
gateway" my problem was solved.

Thanks again.

Hi Tony,
To summarize the steps. You were initially not able to access the internet.
You then checked the "use default gateway on remote network" option and were
able to access the net. You then unchecked this option but were still able
to access internet. Am i right?

thanks
Aanand
