Sign up with GoogleI've got a bit of a issue with a VPN connection. I wonder if anyone can give some advice..
I've got a few pc's/laptops on our network that cannot access my network via a vpn connection. And others where it works fine.
What happens is, the VPN connection gets established, authenticates, and gets all the relevant DHCP addresses assigned. Everything looks good. But certain machines can access the recources on the lan with no issues, and others can't, they cant even ping the router's internal IP. The VPN connection is established, it shows as connected on both the pc, as well as the microtik that controls the VPN access, but no traffic.
The network looks pretty much as follows....
1x Mikrotik with a DSL router in bridged mode, used by selected people in the company as their gateway (Mikrotik controls the dial up, also configured with the VPN details for the various users, and running a dynamic dns to enable access from outside)
1x Draytek with 3 DSL routers, for load balancing, this is my default gateway. (Also running dynamic dns)
1x Linux Proxy server sitting between the Draytek and the rest of the lan (Mikrotik bypasses the proxy)
Server 2008 Domain Controller.
Server 2008 Exchange Server.
A few other random servers.
The mikrotik assigns IP's based on the authentication details used to connect via VPN.
I've taken one user, and setup the vpn connection on his pc with his 3g Modem.
It established the connection, authenticates, gets all the correct DHCP details. But thats it.. Nothing goes through the vpn, so I cannot ping anything on my lan, either by ip or hostname.
I then took the same modem, with same sim card, and tried it on another pc. With the same details and vpn user as before. It connected fine and pinged as expected.
The one laptop that was unable to connect properly has been reformatted, reinstalled, and tested again before any antivirus, or any other software was installed. Still no luck.
We've tried with firewalls on or off, makes no difference. Malware Bytes anti Malware was run, full system virus scans. Even comparing the routing tables yielded no difference between a machine that works and one that doesnt.
If anyones got some idea's, I'd really appreciate it.
