Hello everyone
I have a problem with my smeserver 7.4 with all updates installed.
Both servers are configured as a server gateway-private.
problem relates to the VPN PPTP connection:
I can connect regularly but once connected I can only access the server and everything after that is the gateway. I can not contact any computer on the local network.
Search the forums I found this similar post and this bug report.

http://bugs.contribs.org/show_bug.cgi?id=549
However, following the signs of the bug I've set the mru and mtu but the problem remains.
This is the log when I connect and when I get disconnected.

I hope someone can help me.

This is a client configuration issue (nothing to do with SME server). Either set the client to send default route over the VPN, or add a specific network route after the VPN link is up.

Hi CharlieBrady
thanks for your reply.
I do not think it's the fault of the client, as I did du test with multiple operating systems, Windows XP, Ubuntu, and nothing has changed ...
why I believe it can be a problem on the server, but I can not understand what can be ... :-(
thanks again
Leonardo

Then I suggest you follow Charlies advice.

From the connection log above, your local network is 192.168.65.0 and remote (SME) network is 192.168.66.0
Make sure that subnet mask on both network is set correctly to 255.255.255.0 and NOT to 255.255.something.else.

I don't care how many different clients you use, but client routing is still the job of the client. PPTP just establishes a link directly between the client and the server. If you want other traffic to be routed via that link, then the client must be configured to send that traffic.
