The LAN network of the remote client is My general advice is to avoid the IP ranges like This can be done in less than 15 minutes. On your Windows 7 machine open the admin command prompt and type:.
I like to specify mask by myself, although you can avoid it for hosts. Keep in mind that permanent routes can be added only by local admins. Any user can add temporary routes without -p.
I think it will be better to change the IP ranges used by my remote clients for another that is not so common. RouterOS v6. I wrote those materials more then a year ago for MUM Serbia However, I will upgrade all routers in my virtual lab to the latest version, so you can expect the newer screenshots in the further articles.
I still have a few unpublished articles from the IPSec series. This is a well know problem due the protocol specification. The problem exists as both the server and the client using the predefined fixed ports. Therefore, the first device that pass through the NAT router will occupy these ports for itself. We already discussed how to connect two sites using IPSec tunnel.
In this scenario, we are using either Windows clients or mobile devices based on Android or Apple […]. You are commenting using your WordPress. You are commenting using your Google account.

We finished the server side. Now we can configure the client side. Connecting the TFC router Again, we will refer to the previous article. Until then, enjoy reading my blog. I have read many topics on this forum and couldn't find a clear path to configure IPsec VPN and it seems like the wiki pages are lacking some details.
I would appreciate any help from someone who already experienced the same issues and could share some deeper details on how to configure IPsec VPN to allow different clients to connect.
Thanks in advance everybody. There exist some sample configurations on strongswan pages that are win7 compatible inkl. You have much more options for tuning and compatibility when directly editing your configuration. And with those directories, configuration is preserved during updates. Mac depends on version.
Some are known to have issues with VPN. We will not cover this part here, as I just finished the mini-series related to the client side setup. You can find detailed information for:. After a while, both clients are connected to the Contoso router. Moreover, it is possible to simulate low quality links with data loss even in the lab environment. Again, we will refer to the previous article. We manually made the 0. This approach is correct and we can use it even here. It can be either static or dynamic and all foreign users will use the same pre-shared key.
In our case, we just updated the pre-shared key and authentication algorithm within the peer definition. I would strongly encourage you to do so.
When we make these changes, the TFC router will establish a connection. If we check the policies on the Contoso router, we will see dynamically generated policy for the TFC network.
For this example I will not prepare any special text file with commands. Commands are very simple and we executing them only on the Contoso router:. The first line will delete previous static definition, if any exists. However, you can omit this command and still use that definition. In any case, please check the settings. This will generate dynamic policy for peer 0. The third line will reconfigure the default proposal to support a wider range of authentication and encryption algorithms.
Now you can simulate it in your lab. Try to change different parameters and see what will happen. Now, when you know how to configure different clients and the server side, you should abandon those ancient PPTP connections. First we will need to setup the mobile clients network and authentication methods. Save your settings and select Create Phase1 when it appears.
Then enter the Mobile Client Phase 1 setting.
