Unable to access internet through PPTP connection

SystemAdministrator1
Hi,

I have a UTM220 with firmware:9.102-8

It currently has a PPTP VPN setup.

The VPN works fine, I can connect and access everything but the internet. I want users to access the internet through the VPN tunnel not through their local network.

I am at a loss where to troubleshoot this. All I can think of is maybe I need some kind of static route on the UTM?

Cheers,

    The UTM is setup to pass DHCP over to our internal DHCP server

    In my experience, it's not a best practice to give a VPN user an IP in "Internal (Network)."  I realize that it works sometimes.

    Cheers - Bob

    OK, I am now using the default PPTP VPN pool on the UTM (10.242.1.0/24). 

    I have created two rules on the firewall. 

    1. Source: VPN Pool, Services: Any, Destination: Any
    2. Source: Internal (network), Services: Any, Destination: VPN Pool

    No traffic seems to be blocked, But I am still unable to access the Internet.

    But I am yet to create the masquerading rule as I am a little unsure on them. I have never dealt with them before. Do you guys have any handy doco/guides?

    Cheers,

    Jake.

    OK, so I setup a masquerading rule VPN Pool > External

    Now the Internet works! sweet!

    Can anyone explain why you need the masquerading rule? I don't understand why it is necessary?

    To anyone who is experiencing the same issue here is a link to a great little guide I wish I had found earlier [:$]

    Thank you Barry and Bob for your assistance.
